25. Matthew Stafford, Detroit Lions
Previous Rank: No. 20
Matthew Stafford and the Detroit Lions aren't having the type of season they envisioned. Offensively, Detroit is struggling to find the end zone. Stafford has only thrown three touchdown passes, compared to the 11 he threw in the first four games of the 2011 season.
24. Drew Brees, New Orleans Saints
Previous Rank: N/A
Drew Brees showed this past weekend that he's still one of the top quarterbacks in the league. However, he'll have a hard time remaining in contention for the MVP award if the New Orleans Saints keep losing.
23. Alfred Morris, Washington Redskins
Previous Rank: N/A
Robert Griffin III is getting all the attention, but Alfred Morris is also having an excellent season. He continues to get the bulk of the carries and is taking advantage of his touches. On the season, Morris is averaging 4.6 yard per carry.
22. Tim Jennings, Chicago Bears
Previous Rank: No. 22
Tim Jennings leads the NFL in interceptions. He's doing a good job reading the quarterback's eyes and quickly breaking on the ball. Because of the Chicago Bears' aggressive defense, there's a good chance Jennings finishes the season with a high number of interceptions.
21. Calais Campbell, Arizona Cardinals
Previous Rank: No. 21
Calais Campbell is an excellent all-around football player, as he excels at stuffing the run and generating pressure on the quarterback. The issue facing Campbell is that he might not register enough sacks to remain in the top 25 of the MVP race.
20. Marshawn Lynch, Seattle Seahawks
Previous Rank: N/A
Marshawn Lynch's production is so much more impressive because the opponent knows the Seattle Seahawks want to feed him the ball. While Russell Wilson is having a nice season, he doesn't scare defenses enough to pull defenders out of the box.
19. C.J. Spiller, Buffalo Bills
Previous Rank: No. 7
This weekend showed a glimpse of how the Buffalo Bills plan on using both Fred Jackson and C.J. Spiller. The fact that Spiller won't be getting the majority of the carries really hurts his MVP chances. He has the talent to win the award, but he needs the touches.
18. Reggie Bush, Miami Dolphins
Previous Rank: No. 19
Despite having a banged-up knee and playing a tough Arizona Cardinals defense, Reggie Bush managed to register 67 yards. Bush's ability to fight through this injury helps his chances to win the MVP award. His durability has always been a question mark, but this is a positive sign.
17. Eli Manning, New York Giants
Previous Rank: No. 13
Eli Manning isn't quite having the season he expected, as he's had some up-and-down performances. However, he's still putting up good numbers and helping the New York Giants win football games.
16. Jamaal Charles, Kansas City Chiefs
Previous Rank: No. 17
Jamaal Charles is on a roll right now and making a major move in the MVP race. He looks to be fully recovered from last season's knee injury. So much of Charles' game depends on his speed and quickness. This is why he needs to be fully healthy in order to be effective.
15. Ben Roethlisberger, Pittsburgh Steelers
Previous Rank: No. 12
Ben Roethlisberger had a bye last week, but has done enough in past weeks to remain in the MVP hunt. The Pittsburgh Steelers' lack of a running game means Roethlisberger will have plenty of opportunities to put up big numbers.
14. Arian Foster, Houston Texans
Previous Rank: No. 2
The Houston Texans continue to make Arian Foster the focal point of their offense. This means he gets plenty of opportunities to pick up yardage and score touchdowns. However, it also hurts his yards-per-carry average. His 3.7 yards per carry is the main reason he dropped in the ranking.
13. Clay Matthews, Green Bay Packers
Previous Rank: No. 6
Clay Matthews is on pace to have the best statistical season of his career. He has been able to register a sack in every game this season, except for one. Matthews' ability to generate pressure on the quarterback is a major key to the Green Bay Packers' success.
12. Peyton Manning, Denver Broncos
Previous Rank: No. 16
The more time Peyton Manning has to develop a relationship with his weapons, the more success he'll find. Manning is also still trying to work off the rust from missing an entire season due to injury. His performance against the Oakland Raiders could be the start of a run.
11. Victor Cruz, New York Giants
Previous Rank: No. 15
Despite some drops in the first game of the season, Victor Cruz has been one of the more explosive playmakers in the NFL. He has been able to provide Eli Manning with a reliable target and big-play threat. Cruz is proving that last year's success wasn't a fluke.
