lynch at 5? he carried the offense in seattle all season.. LOL
Forte has carried the Bears offense pretty much the whole time he has been here with little help save for this season. There were a few seasons where he accounted for the highest percentage of his teams yards than anyone player other than a QB.
As for Seattle, Wilson had 26 TDs, a 63.5% completion percentage, and a 101.2 passer rating. He makes plays when he needs too and avoids making mistakes. His game is about efficiency. Incidentally, Cutler has only exceeded 26 TDs once (he had 27 in 2009) and has never had a passer rating close to 101.2. The closet he got is the 89.2 he put up this year.
You can be an effective QB without putting up big numbers especially when you know you have a good enough D and running game that you don't need to take unnecessary risks in the passing game.
