1. Adrian Peterson: I know some of you where expecting Chris Johnson but if you think about defenses will have more attention on him this year and don't get me wrong he is a top 5 back but just not #1. Adrian Peterson was disappointing this year to say the least defenses main target was adrain peterson no matter how good of a year that the old gunslinger had and if brett favre stays next year then defenses will be more focused on Brett Favre which will take pressure off of Adrian Peterson and I predict Adrian Peterson will have huge year.
2. Chris Johnson: The dude is fast what more can you say! he had over 2000 yards this year he can catch the ball and run with the football and with vince young taking a little more pressure off of him he could have a another great year (not over 2000 yards rushing next year)
3.Ray Rice: He Runs Hard he can break free of almost any tackle and he catches the ball better the some receivers. He kinda reminds me of Walter Peyton (when he runs hard) and Marshal Faulk ( his size and his catching ability) he was a top 10 back this year and Derrick Mason might retire this year so expect them to get a whole lot more carries and a lot more screen passes.
4. Jaamal Charles: He's Kinda like Chris Johnson very fast and at the end of the season he put on a show running for a chiefs rushing record and I think he will blend in perfectly in Charlie Wies System and he's #4 on this list but i would not be surprised if he was number one at the end of next season.
5. Cedric Benson: This guy was unbelievable last year after being cast out of chicago he showed why he was a top 5 pick in the draft. He like ray rice runs hard and the bengals don't have receiver that stretches the field and with Chad Ocho Cinco (or Chad Johnson) and Lavuarnes Coles aging he might get more carries then he did last year which will make him even more productive sense he was top 10 in carries last year.
