Some interesting thoughts...except the idea that Cutler would ever accept being a back-up. Not a chance. If we forced his hand and tagged him, he would...but that would be the only way.
1. Love what I've seen from Josh. But, only 2 games of material isn't enough yet. Even if he isn't all that, he still is enough to be a 100% legit back-up that contributes as a quasi-coach.
2. If we see more of McCown due to Cutler's injury, and he continues to look great, then the club may have a tough decision. McCown would be a bargain compared to Cutler.
As much as I loved seeing what McCown did, I don't see the team moving away from Cutler for McCown. I just want Josh as a back-up. It's good to know we have someone of quality to hold down the fort. And as you mentioned, maybe the staff might not be afraid to bench Jay for the remainder of a game if he throws up a stinker.
