I don't think it would help.
Mike Martz has done a very poor job with Chicago this season. Yeah I know they had success with Cutler some time this year, but they also had a down side proving they are what you thought they were. When I heard Martz comparing Forte to Marshall Faulk, I knew something would come back and bite them on the ***, and it has nothing to do with "karma" like some Rams fans I know were saying, it has to do with a poor management to a back up quarterback.
The Bears are done, even if Cutler comes back.
Think about it.
They throw in Hanie, and keep running the same style offense. If we can't complete a pass, just run every down since after all, Matt Forte is Marshall Faulk 2.0. Once Forte is out, they panicked cause they knew that was the finishing blow.
When Cutler went down, they didn't change a beat. They expected a back up to step in and make all the right moves. Not only does Hanie suck, but they should have got the message that he's not a quarterback you should trust to pass so many times a game. Mike Martz got all that praise when they were winning, he deserves as much flak as praise, since they are losing and he refuses to try to mold something about a back up quarterback, he just expects him to pick it up eventually.
It don't matter if Cutler comes back, the entire league has seen they refuse to change their offensive style around Hanie, so when Cutler comes back, nothing will have changed, no need to worry. By now you can expect, if Cutler comes back, they'll still have trouble cause teams have studied them. They don't change their stuff up like an elite offense, so they are bound to keep losing even if he comes back. It's not that hard to shut them down. We did it in the playoffs. My saying is, for every WR Martz adds, that's another hole for an LB to rush Cutler.
