I don't say this too often for players, and I hope the length isn't too long as RBs definitely have the shortest "life span" of all the positions in the NFL, but if there's one guy who I want to see get paid on that team, it's Forte. The guy didn't holdout for an extension like 95% of other players do. He played in camp and is playing in the pre-season. Hasn't said one word about contract talks unless a reporter keeps asking him about it (and usually he'll just say he leaves that to his agent anyway/wants to just play football and not talk about it) and has just been a pure professional through and through with fans, the media, management, etc and just bust his ass off.
Pay the man.
