1. S Eric Berry
Although he barely played in 2011, Berry made a big impact in 2010 and quickly was regarded as one of the best safeties in the league today.
If he manages to stay on the field in 2012, he could earn himself Pro Bowl and All-Pro honors as he tries to bounce back.
2. OLB Justin Houston
Houston stepped up in the second half of last season with 5.5 sacks, finishing second on the team. If Houston continues to help Hali provide a dangerous pass rush, Kansas City's defense could be one of the best in 2012.
3. S Kendrick Lewis
For a fifth-round pick, Lewis has done a lot for Kansas City at the safety position. Now that he has two years under his belt, he hopes that his third season will be his best.
He will have Berry back and the Chiefs pass rush is set to do big things to help out all of the defensive backs.
4. G Jon Asamoah
Asamoah has not made a name for himself in the league, but not many offensive linemen do since they don't accumulate notable statistics.
Asamoah's best statistic is giving up only three sacks and committing only four penalties in 2011 in his first full season starting at guard.
5. K Ryan Succop
Succop found a rhythm of helping Kansas City in 2012 when their offense was not at its best. After not being able to take the ball to the end zone for a touchdown, Succop was successful, connecting on 21 consecutive field goals.
The Chiefs hope their established kicker can carry this over after signing a five-year contract extension.
6. RB/WR/KR/PR Dexter McCluster
McCluster has a lot of potential and the Chiefs will need him to shine this season. McCluster has shown off his abilities a couple of times.
If McCluster can be consistent as a returner and come through in the passing game, he will help make the 2010 draft class look great.
7. TE Tony Moeaki
Like Berry, Moeaki did a couple of things in 2010 to help contribute to Kansas City's AFC West title run.
It's hard to remain optimistic about Moeaki's health, but if he stays on the field, he can be a dangerous tight end and give Cassel another weapon in the passing game.
8. WR Jonathan Baldwin
He may have a lot to prove still, but the decision to select Baldwin was a good one by the Chiefs in 2011.
The Chiefs are set up to have a good offense this season and Baldwin can play a big role in making that happen.
9. CB/KR/PR Javier Arenas
Arenas has had a couple of flashes on all three phases of the game. He has had some good punt returns, not letting defenders take him down easily. As a nickel cornerback, he improved in 2011 with two interceptions and two sacks.
As for offense, he has entered the game as a Wildcat quarterback and scored one touchdown on the ground in 2011.
10. DE Allen Bailey
Being drafted in the third round, Bailey contributed in the shocking victory against the Green Bay Packers.
Bailey took advantage of some of the absent offensive tackles and sacked Aaron Rodgers in the fourth quarter. The sack was a nine-yard loss on a third-down play. Bailey also helped occupy the substitutes at offensive tackle to allow Hali to get to Rodgers.
