INDIANAPOLIS —** Sefo Liufau knows he needs to take any opportunity available to him to prove he can play in the NFL.

The former Colorado quarterback has heard the questions he must answer about his throwing ability, so Liufau signed up to throw to running backs, defensive backs and linebackers at the Combine to put more repetitions in front of coaches' eyes.

"I think the biggest question coming in — and honestly one of my weaknesses — is being able to be consistently accurate," Liufau said. "I think that's really big for me and showing teams that I can go out there and I can throw the ball [with] great consistency."

After helping drive his Buffaloes to their best season in 15 years to cap his collegiate career, Liufau is relentlessly driven to show scouts and NFL coaches that he can grow beyond what's on his tape and transition to the next level.

"The biggest thing is accuracy and that comes from getting my shoulders and my feet in the right spot and being able to do it subconsciously and being able to do it consistently all the time," Liufau said. "In the NFL, I think the first thing is probably accuracy. You can probably flip on the tape and I make a lot of great throws, and on the flip side you can see a lot of throws that are like, 'What the heck? This guy sucks!' So [my focus is] just being able to be consistent and get the ball to my playmakers."

Throwing to other position groups throughout the week is just the most recent step for Liufau, who has been working out in Portland, Oregon, to prepare for the Combine, the upcoming Colorado Pro Day and his NFL future. Liufau also had the opportunity to show his progress at the Senior Bowl in front of the Chicago Bears' coaching staff, which coached the North team, and numerous scouts from around the league.

Analysts do not anticipate Liufau's name to be called during the draft's first two days, but through his work to shore up his mechanics and consistency, he could quiet the skeptics and make the impression that drives an NFL team to take a flier on him with a late-round selection.

"[I can quiet questions about my arm talent] just by showing it here and at the Pro Day next Wednesday," he said. "And when I hopefully get the opportunity to possibly make a team, show it in camp. I think the most important people to impress are those teams and they know that's what my goal is."
