As we wrap up our week's preview of the running backs available in the 2012 NFL Draft, let's take a look back at who the Broncos have drafted at those positions.

Player:Knowshon Moreno
Year Drafted:2009
Round:1 - 12 Overall
College:Georgia

Broncos Career:Through his first three years, Moreno has gained 1,905 yards on 466 carries (4.1 avg.). He's appeared in 36 games with 24 starts and has totaled 18 touchdowns (12 rushing / 6 receiving).

Player:Clinton Portis
Year Drafted:2002
Round:2 - 51 Overall
College:Miami (Fla.)

Broncos Career:Portis made his impact felt immediately his rookie season, rushing for 1,508 yards and scoring 17 total touchdowns. Those numbers earned him the AP Rookie of Year Award. He followed up his rookie campaign with a stellar second season in which he ran for 1,591 yards, earning a Pro Bowl nod. His Denver career ended in March of 2004 when he was traded to the Washington Redskins for Champ Bailey and a draft choice.

Player:Terrell Davis
Year Drafted:1995
Round:6b - 196 Overall
College: Georgia

Broncos Career:Davis, a three-time Pro Bowl and first-team All Pro selection in 1996-98, finished his career with a franchise-record 7,607 rushing yards and 60 rushing touchdowns in 78 regular season games as a key member of the Broncos' back-to-back Super Bowl championship teams. In 1998, he rushed for 2,008 yards, the fourth most rushing yards in a season in NFL history, to earn league MVP honors. Davis was inducted to the Broncos' Ring of Fame in 2007.

Player:Bobby Humphrey
Year Drafted:1989
Round:1 - Supplemental Draft
College:Alabama

Broncos Career:When the Broncos selected Humphrey in the 1989 Supplemental Draft, the hope was he would be the perfect complement to John Elway and the passing game. That hope came true his rookie season as the former Crimson Tide standout rushed for 1,151 yards and helped the team reach Super Bowl XXIV. He added to that total the following year with 1,202 yards rushing and was named to the Pro Bowl. A contract dispute in 1991 limited his action to just four games and the following season he was traded to Miami.

Player:Otis Armstrong
Year Drafted:1973
Round:1 - 9 Overall
College:Purdue

Broncos Career:After leaving Purdue as the school's all-time leading rusher, Armstrong only rushed for 90 yards his rookie year. The following year, he nearly doubled that total in the first two games on his way to a league high 1,407 rushing yards. He finished his Broncos career with 4,453 rushing yards, 123 receptions for 1,302 receiving yards, 879 yards from kickoff returns and 32 total touchdowns.

Player:Floyd Little
Year Drafted:1967
Round:1 - 6 Overall
College:Syracuse

Broncos Career:Little was the first No. 1 draft pick ever signed by the Broncos and was widely regarded as "The Franchise." That was a billing he easily lived up to by leading the Broncos in rushing from 1967 to 1973 and rewriting the Broncos' rushing record book. At the time of his retirement, Little ranked seventh in NFL annals in career rushing yards. Little was named to the Pro Football Hall of Fame Class of 2010 and was one of the four original Denver Broncos Ring of Fame inductees. His jersey No. 44 is one of three retired by the organization.
