Despite his age (he'll be 30 next season), Bennett's performance for the Patriots ensures he will be in high demand -- if the Patriots let him test the market. New England's massive cap room and Rob Gronkowski's extensive injury history could make this a franchise-tag situation.

Cook exploded in his first postseason as a pro, catching 18 passes for 229 yards and two touchdowns in the Packers' run to the NFC Championship Game -- an appearance made possible by Cook's clutch sideline catch in the waning seconds of regulation against the Cowboys to set up Mason Crosby's game-winning field goal. As with Bennett, Cook will turn 30 this spring, but now that he's shown the potential he long seemed to possess, he'll be in demand -- even though the best situation for him would likely be a return to Green Bay to build on his budding partnership with Aaron Rodgers.

Doyle ruled in a breakthrough 2016 season that saw him comfortably exceed the reception, yardage and touchdown totals of his first three seasons combined. A reliable underneath target for Andrew Luck, the 6-foot-6, 267-pounder has good size -- and the ability to use it effectively.

It's not a question of whether Cameron is good enough. It's about four concussions in four seasons, most recently last Sept. 25, which ended his season and could end his career. Cameron made a Pro Bowl with Cleveland and picks up first downs on 37.5 percent of his career receptions, but those attributes are secondary to his health concerns.

Despite infrequent playing time behind Zack Ertz, Burton was effective when called upon, finishing with 327 yards on 37 receptions -- 23 of which came in the final six games of the 2016 season. He's also an improving blocker.

A good complement to Jimmy Graham, Willson has career averages of 13.2 yards per catch and one touchdown every 10.6 receptions. He should be able to get more playing time and better production if he moves on in free agency.

At 32, Fasano's pass-catching production is down, but he remains one of the league's best blockers at the position.

Still reasonably productive, Gresham has missed just one regular-season game since undergoing surgery for a herniated disc in his back two years ago. That surgery kept him on the market much longer than expected, but he should find a landing spot quicker this time around.

He had career highs in receptions and yardage in 2016, but he also dropped one of every 11 catchable passes (five drops in 55 on-target passes). He's an average blocker for his position who should at least be part of a two-tight end rotation.

One of the better blockers on the market -- particularly in the running game -- Paulsen has also allowed just one sack in the last two seasons, according to ProFootballFocus.com.

Sims had some solid production last year after being pressed into more extensive work following Jordan Cameron's season-ending concussion, and at 6-foot-4 and 271 pounds, he has some still-untapped potential as a blocker.

A torn ACL ended his contract year before it began and temporarily blocked his improvement as a run blocker, but he should get another shot this season.

The former Bronco had a good bounce-back year in his return to his hometown, catching 44 passes for 583 yards and two touchdowns with the Redskins last year. At 33, he's a good complement to Jordan Reed and the Redskins would be wise to bring him back for 2017.

The late-blooming former European pro basketball standout isn't yet eligible for unrestricted free agency -- even though he turns 31 in April. He showed a spark in Arizona, particularly the last two seasons, and has a career average of 13.4 yards per reception, but his age is working against him, even though he has little of the long-term wear and tear other players of his age possess.

The expected passing of the torch from certain Hall of Famer Jason Witten to Escobar in Dallas never happened, and Escobar remains untested and unproven, with just 30 receptions in four seasons -- but he has eight touchdowns, giving him one score every 3.75 receptions.

As the only player in NFL history with at least 6,000 yards from scrimmage and an average of 128 or more yards per game in his first four seasons, Bell will be coveted -- if the Steelers let him hit the market. The franchise-tag figure for running backs is expected to come in at around $9.7 million -- a perfectly reasonable figure for a runner of Bell's quality. It would be a shock if the Steelers don't use it on the two-time Pro Bowler.

Is his 2016 ankle injury a sign that pre-draft injury concerns have caught up to him, or was it a blip? The answer will depend on how well he rehabs -- and what sort of shape he is in once his recovery is complete.

He's productive and a solid No. 1 running back, but you'd like to see more consistency; in 39 career games with at least one carry, he's mustered more than 4.0 yards per attempt in just 18 of them.

He probably isn't full-time starter material, but his strong, determined work in relief of Doug Martin last season and relatively low mileage should give the 5-foot-6 back an NFL home for the foreseeable future.

Last year marked his first 1,000-yard season since 2010, but it took 299 carries for him to break four figures, as he averaged fewer than 4.0 yards per carry for just the second time in his seven-season career. He's a goal-line monster, scoring 18 touchdowns, but the best fit for him -- by far -- is the team for which he currently plays.

Crowell was often all that separated the Browns' offense from disaster last season, racking up 1,271 yards from scrimmage while averaging 4.8 yards per rush and 8.0 yards on his 40 receptions. But he had a tendency to get most of his yards in clumps; ProFootballFocus.com pointed out that 47.5 percent of Crowell's rushing yardage last year came on 16 carries.

If you owned LeSean McCoy in fantasy, you probably cursed Gillislee's name a few times last season, as he scored nine touchdowns -- one for every 11 touches he had. He was the perfect complement to McCoy -- explosive, elusive and reliable. He fumbled just once in 110 touches.

The Ravens' leading rusher is a restricted free agent who might not get a high tender with Kenneth Dixon waiting in the wings. West isn't a chain-mover, but is sturdy between the tackles.

Bengals head coach Marvin Lewis has indicated he wants to bring Burkhead back, and with an average of 4.6 yards per carry and 8.5 yards per reception last year, he's delivered in limited work. Someone might be willing to give the 26-year-old Nebraska product a greater role than Cincinnati can.

Age (32) and a torn ACL work against him, and he has now missed 27 of the last 48 games because of various injuries. When healthy, he's still arguably the best receiving running back in the game. In his four seasons in San Diego under then-head coach Mike McCoy, he averaged 4.5 receptions per game, the second-most of any running back with at least 100 catches since 2013.

In 2015, the Steelers had no dropoff when forced to turn to Williams when Le'Veon Bell was injured. He's still reasonably productive when needed, and he is a quality locker-room presence, but he turns 34 in April.

Declining production and advancing age (33 next month) led the Giants to release him this week. Jennings' historically steady production dipped last year, and although he has just seven career fumbles in 1,221 career touches, he might have to wait a while for his next contract.

Muppets jokes aside, the 28-year-old Whittaker has always been productive in limited work, and had a career-best 491 yards from scrimmage on 57 attempts and 25 receptions last year.

A torn Achilles tendon ended his 2016 campaign in the preseason, but if he recovers, the Chargers seem likely to bring him back, especially with Woodhead expected to hit the market.

Turbin was effective as a target out of the backfield for the Colts last year, and might have added another two or three years to his career by showing what he could do in space as a receiving target.

In the last two years, he hasn't recaptured his production from the 2013-14 seasons with the Buccaneers, when he was a dependable relief option for Doug Martin. He's relatively fresh, but turns 30 during the season.

He's trending in the wrong direction, with steadily declining production following a rookie season in 2013 in which he gained 1,023 yards from scrimmage on just 157 touches (a 6.52-yard average). Last year, he averaged just 3.93 yards per touch -- and 2.82 yards per carry.

He's effective catching passes out of the backfield, but a career 3.5-yards-per-carry average -- including 3.3 in 2016 -- means he's only viable as a backup option.

Despite 7,537 career yards from scrimmage in nine seasons, his career remains one of the great might-have-beens in recent NFL history, as he hasn't been the same since foot problems struck in 2011. McFadden's average per carry has hovered at 3.6 yards or worse in four of his last five seasons.

He's just a year removed from leading a world champion in rushing, and should eventually land in someone's camp with a shot at joining their rotation.

The complete package at fullback. Baltimore began finding more ways to use him in 2016 and whether he returns to the Ravens or moves on, the team that adds him will likely incorporate him into the offense as much as possible, since he's a quality target as well as a devastating blocker.

LeGarrette Blount owes Develin a debt of gratitude for giving just enough space for the tailback to score 18 times this year, most from short-yardage situations with Develin as the lead blocker.

A 31-yard reception in the NFC Championship Game showed DiMarco's skills with the football, and his blocking was an underrated aspect of the Falcons' powerful 1-2 backfield punch of Devonta Freeman and Tevin Coleman.

New Bills offensive coordinator Rick Dennison likes to utilize the fullback, and if he doesn't like his chances of finding a free-agency upgrade, there's ample reason to bring Felton back, starting with the production of LeSean McCoy and Mike Gillislee working behind him.

The Seahawks need all the quality blockers they can find -- even if they aren't on the offensive line -- so bringing back the 31-year-old former Raiders standout seems like a logical move.

A converted tailback, Line was less effective last year without Adrian Peterson in the backfield -- which is understandable. Minnesota could opt to get younger and look for more power from the position.

Having long since proved that he's not a product of Peyton Manning in Indianapolis, the durable Garçon had his highest per-catch average in four years last season (13.2 yards) and has more receptions in the last four years than all but six players. Other receivers have more sizzle, but with Garçon, you know what you're going to get: precise routes and steady production. At 30, he's aging well and should have plenty left in the tank.

He's missed 11 games in the last two seasons and got caught up in the Bears' offensive struggles, particularly last year, when he caught 52 passes -- his lowest total since his his rookie season. He's still capable of stretching the field, and if he can stay healthy, should be able to reach his 2013-14 peak production once again.

Four 100-yard games in the last six weeks of the 2016 season pushed him over 1,000 yards for the fifth time in nine seasons and showed that he still has the same explosiveness he's always possessed. You have to accept that he will likely miss at least a bit of time because of injuries; he's only made it through a full 16-game schedule once in the last eight campaigns, and has missed 14 games over the last five seasons, but there are few better speed threats in the NFL.

The Browns' massive cap room means there's no reason why they can't fit Pryor on their roster, even if they have to use the franchise tag. He's still developing as a wide receiver, but he had 1,007 yards on 77 receptions last year in spite of Cleveland's lingering QB issues. What could he do with a strong triggerman?

Quietly productive, the Minnesota State product had a breakthrough season last year, working mostly in the slot to catch 69 passes for 967 yards and five touchdowns. A 12-catch, 202-yard game against the Packers in Week 16 punctuated his season. If the Vikings lowball him on their offer sheet, someone will up the ante on Thielen, who appears ready to break into the ranks of the NFL's perennially productive receivers.

The 6-foot-3, 205-pounder capitalized off injuries to emerge as a solid target for Philip Rivers last year, notching 810 yards and four touchdowns on 58 receptions. But at 28, he's older than a typical restricted free agent, because he spent two seasons with the CFL's Toronto Argonauts before he made the jump to the Chargers in 2014. So his long-term upside might be limited compared to other three-year veterans.

Britt notched his first career 1,000-yard campaign in his eighth NFL season despite the Rams' issues at quarterback with Case Keenum and Jared Goff splitting the season. Britt played for Jeff Fisher in Tennessee, St. Louis and Los Angeles, and that connection might ensure the Rams decided to move on as they try to remove as much as they can from their struggles of recent years.

A day after the 2016 season, Wright declared that he would not be a part of the Titans going forward, and that's probably just as well. His numbers declined the last two years as the Titans moved toward their run-heavy "exotic smashmouth" attack, which limited opportunities for Wright as a slot receiver. He'll also have to show that the tardiness that made him a healthy scratch from the Titans' Week 14 win over the Broncos is a one-time thing, and not a sign of deeper issues.

A solid bounce-back season after he struggled in 2015 got him on the right track, and offered assurance that his career-worst campaign of 2015 was an aberration. Stills can stretch the field, evidenced by his career average of 16.7 yards per reception. Dropped passes remain a problem, however.

One of the few bright spots in the 49ers' dismal season, Kerley posted 664 yards and three touchdowns on a career-best 64 receptions in his first year starting more than half of the games in the season. Kerley's status is just part of a series of broader questions for the 49ers at wide receiver, as Quinton Patton and Rod Streater join Kerley in being eligible for unrestricted free agency. New GM John Lynch and head coach Kyle Shanahan could opt to overhaul the entire position group.

It's not about his production as a wide receiver, but his explosive capability on special teams. Patterson has yet to reach his potential on offense. Although he grabbed a career-high 52 passes last season, he averaged just 8.7 yards per reception. But his whopping 30.4-yard kickoff average for his career -- with an average of one touchdown every 26.8 returns -- will draw some interest around the league, especially among teams who return kickoffs at a higher rate than others.

His talent is undeniable, reflected by a 17.1-yard career per-catch average and 2,754 yards and 14 touchdowns on 161 receptions over just 35 career games. But he hasn't played a regular-season game since 2014 because of alcohol issues, and his expected return last year was scuttled by a stint in an in-patient rehabilitation facility just as he neared eligibility to return. Only a team with a strong support infrastructure, a mature locker room and depth at receiver will be in position to take a chance on Gordon.

His single season in Cincinnati -- 862 yards and six touchdowns on 64 catches -- was in line with his 2014 production as a Patriot, but those two campaigns sandwiched a disappointing 2015 season that led to his departure from New England. LaFell is a decent complementary receiver, and could represent good value a week or two into the signing period -- even though he should end up getting more than the one-year, $2.5 million deal under which he played last season.

Boldin turned 36 during the season and isn't the downfield threat he once was; last season he averaged just 8.7 yards per reception, but did grab eight touchdown catches in a 67-catch, 584-yard season. His age and lack of speed probably ensures he'll linger on the market, but as a complementary target, he's still viable and capable of adding to career totals that should, at minimum, make him a finalist for the Pro Football Hall of Fame.

Floyd was enduring the most disappointing season of his career prior to a DUI arrest in Arizona that led to his release, and in the past three seasons his performance has not matched his potential. A 1,041-yard season in 2013 remains the only time he's cracked four figures in a single season.

The Falcons aren't likely to let Gabriel loose after he emerged in the second half of the 2016 season; in the 12 games from Week 8 through Super Bowl LI, Gabriel caught 36 passes for 743 yards and six touchdowns, which would put him on nearly a 1,000-yard pace for a 16-game season.

A change of scenery might be the best thing for Woods, who has just three 100-yard performances in 57 career games and has not lived up to his potential in a series of steady, but unspectacular seasons -- all with between 40 and 65 receptions and 550 to 700 yards.

A product of Colorado Springs' Wasson High School and Northern Colorado, the 34-year-old Jackson's production has dipped because of injuries the last two seasons that limited him to just 15 games in that span. Prior to the last two seasons, Jackson notched six 1,000-yard campaigns in a seven-season span with San Diego and Tampa Bay. How capable is he of using his 6-foot-5, 230-pound frame to his advantage given his advancing age and injury issues?

The return of Steve Smith Sr. to the lineup last year cut into Aiken's numbers last year, and after what he called a "very frustrating" season, he appeared ready to move on once the 2016 season ended. Aiken is a good route-runner who can make plays in traffic and enjoys getting physical, having honed his one-on-one combat skills on kickoff and punt coverage early in his career before making his 2015 breakthrough as a wide receiver.

After missing most of the 2014 season and all of the 2015 campaign with a torn patellar tendon, Cruz wasn't the same player in 2016, finishing with just one touchdown and 586 yards on 39 receptions. At 30 and with his explosiveness uncertain, he'll likely have to play on a short-term prove-it contract in trying to get back to his old form.

Ginn's last two seasons as a wide receiver were his best since 2008, his second campaign in the league. But he'll be 32 in April, and he's started showing his age on returns in recent years; his average of 7.0 yards per punt return in 2016 was his worst since 2009 and was 3.5 yards below his career average.

Teammate Brice Butler is also an unrestricted free agent, and is taller (by one inch) and larger (by five pounds) than the 6-foot-2, 210-pound Williams. But Williams is far more productive, he's had steady production of between 594 and 840 yards in each of his four campaigns, and has never missed a regular-season game.

A career-best season last year despite the Rams' quarterback quandary offered evidence of his potential, but he may need a change of scenery to achieve it.

He had some solid production in bursts last year, but also dealt with a pair of concussions during the season. Nevertheless, the vertical threat he poses should earn him a contract somewhere.

After catching just six passes in his first two seasons, Patton had 67 receptions the last two years -- but has just one career touchdown.

It would come as a shock if the Redskins don't re-sign or place the franchise or transition tag on Cousins, but if they choose to do neither and let him test the market, he is a lock to get the biggest contract of anyone available this year, given the dearth of viable starting quarterbacks on the market. Washington can place the tag on Cousins between Feb. 15 and March 1; if they follow their pattern from last year, they'll wait until within a day or two of the deadline before placing any tag on the Pro Bowler.

The playoff meltdown in his final start with the Houston Texans 13 months ago is a scarlet letter on his resume, but he delivered in five starts for the Bears last year, finishing the season with a career-best 98.0 rating on 134-of-200 passing for 1,445 yards, six touchdowns and no interceptions. The four-interception playoff performance for Houston is the aberration; in the last two regular seasons, he has 25 touchdown passes against just seven interceptions. Hoyer isn't going to carry a team on his shoulders, but with a decent supporting cast, he's good enough and consistent enough to warrant a starting role.

The passage of time works against McCown, who turns 38 this July. Nevertheless, a steady 85.9 rating over the last four seasons with the Bears, Buccaneers and Browns ought to compel someone to give him a look as a stopgap; he could be an option for a team that doesn't find a QB of the future in this year's draft to get through the season.

The voiding of his contract last week made Fitzpatrick a free agent, but he is unlikely to find any opportunity that assures him of a starting job after his worst campaign since his rookie season. Fitzpatrick's spiral began in the regular-season finale of the 2015 campaign and never reversed itself, yet because of injury and circumstance, the Jets couldn't fully extract him from their lineup last year. The 12-year veteran was willing to wait until the Jets came back to him last August, and he could be just as willing to sit and wait out the market again this year.

Jameis Winston's arrival in 2015 brought an end to his Tampa Bay opportunity; he hasn't started in the last two seasons and has thrown just 11 regular-season passes. Scattershot preseason performances last summer did not help his cause, and his career sack rate of one every 12.25 pass plays is also a concern. But with a career 84.6 rating, the 27-year-old veteran could be an option with some still-untapped value for a QB-needy team that doesn't like its draft options this year.

He didn't distinguish himself in nine starts with the Rams last year and seems likely to settle in as a long-term backup somewhere. He hasn't matched his early performances in 2013 with Houston over the long term; his rating of 83.7 in the games he started under then-coach Gary Kubiak has become a 76.2 rating in all the games he's played since the Texans dismissed Kubiak late in Keenum's first season as a starter.

Ten interceptions in his final three starts with the Bears last season tarnished what had been a promising beginning to his time as a starter, but his work should be enough to give him an opportunity as a team's clear No. 2 quarterback.

The 49ers had myriad problems last season, but Gabbert didn't do anything to fix them, and despite his first-round pedigree, his middling touchdown-to-interception ratio, 71.5 career rating and completion percentage of 56.0 bellow, "backup."

You know what you're getting with the 37-year-old Hill -- a steady locker-room presence who can play at a league-average level in a pinch. Hill started one game in two years as Minnesota's backup behind Teddy Bridgewater and later Sam Bradford.

Cassel turns 35 in May, and offers more in terms of counsel and assistance in the meeting room than performance on the field, where he has a 69.6 quarterback rating over the last four seasons. His presence and wisdom should ensure him a spot on someone's roster, and it would be no surprise if he's back with the Titans to work behind Marcus Mariota.

In today's edition of Small Sample Size Theatre, we have Nassib, who has a career rating of 152.1 -- on just 10 attempts. He looks the part, and would be an interesting potential signee for the Jaguars -- whose executive vice president in charge of football operations, Tom Coughlin, coached Nassib for three seasons in northern New Jersey.

Manuel's career as a starter failed to launch; he went from 10 starts to four to two to one over his four-season career with the Bills. He's a reclamation project at this point, having struggled in his lone start at the end of the 2016 season when he went 9-of-20 for 86 yards against the Jets. He will have to recalibrate and re-establish himself as a backup.

His work with Atlanta as a backup last season and his pedigree with a similar scheme in Houston under Gary Kubiak make him a potential 49ers target, but he turns 36 this season, and if any team saw him as a starter, it would be only as a placeholder.

With a 2-2 record in four career starts and near-league-average numbers, Jones pretty much fits the mold of a typical backup. The best situation could be staying right where he is -- if the Steelers want him back.

McGloin has told reporters that he wants to go somewhere that will provide a chance to compete for a starting job, but his production in six starts as a rookie and limited opportunities after that fits the profile of a No. 2.

After squandering his chance to become a starter for the defending world champions last summer, the question for Sanchez is whether he can settle in and be content as a reserve, because that's what the 30-year-old quarterback is at this point. If Dallas opts to bring back fellow free agent Kellen Moore among the backups to Dak Prescott, Sanchez will have to move on.

His performance and history of off-field missteps -- most memorably chronicled during the 2014 season of Hard Knocks make any opportunity beyond a chance to compete for a No. 2 job highly unlikely.

He's coming off of a torn anterior cruciate ligament and has just 56 attempts in the last two seasons. There's still some upside, making him an interesting quarterback on which to take a flyer, but no one will hand him anything.

The Cowboys would have been content with Moore as the healthy backup behind Dak Prescott before Moore suffered an ankle injury. Moore is similar in quality and presence to Cowboys coach Jason Garrett back during his playing days.

Philip Rivers' durability limited Clemens to just 10 attempts in the last three seasons. Clemens will be 34 this season and is a dependable reserve, but nothing more.
