Look the Pats sent Cincy a second rounder for Clock killin Corey Dillon, now you are saying that they are going to send more plus have to sign him to a big time contract. I'm calling BS, nothing is more sure in the NFL than saying that a RB will break down long before his contract does. RB is the one position (and kickers) that you can come in as a rookie and be productive. Forte is overrated, in 2009 and 2010 he was 18th in rushing in the league, 18th!! He is only a franchise player for Chicago because they have no offense.
I see no reason to give up on the two guys drafted last year, the average lifespan of a NFL RB is five years, and now you want to spend multiple draft picks and a large amount of salary cap on a guy who has already played five years, no thanks.
