5. S Eric Berry - Berry was highly touted as one of college football's best players. Berry was unable to meet expectations due to his injury taking place early in the season, and will be motivated to make strides after being away from the game for so long.
4. QB Michael Vick - If any player on this list knows anything about making a comeback, it's Vick. The 2010 Comeback Player of the Year could win this award once again after a disappointing season. He can take the award by taking on more of a leadership role and doing his best to keep his team in uniform.
3. RB Adrian Peterson - Peterson and the Vikings had it tough in 2011. Christian Ponder is still learning and will need Peterson back to help lead the offense. Peterson has not been in a position where the Vikings have had to question his desire or his toughness.
2. RB Jamaal Charles - Even when Charles shared the backfield with Thomas Jones in 2010, he managed to finish second in the league in rushing. Charles has a tough task to overcome as most running backs struggle when returning from a torn ACL. But Charles' injury occurring in Week 2 has given him ample time to recover. Defenses have to watch out for his breakaway speed.
1. QB Peyton Manning - Last year was the first time Manning missed a start in his career. Everyone is aware of what Manning is capable of, as he's been one of the most consistent quarterbacks in the regular season for the last decade.
Manning knows that his return won't be easy, but he's still capable of making his receivers look good and that will ultimately lead to success for the Denver Broncos.
