Best Sleeper Pick and why?

Matt Forte (RB CHI). Many cheat sheets have him around 28th overall for RBs. Yes he is a rookie and you should not take too many chances on new meat in the NFL. However, rookie RBs are the most successful players and especially when they have the opportunity to excel. Forte has been given the starting role with the recent release of Cedric Benson. He has only Adrian Peterson pushing him. Forte showed real promise at Tulane and given the ball by Lovie Smith in Chicago, he could easily be a Top 15 RB (especially in NON PPR leagues).
