If he were fired, he'd get another shot after a year or two as an offensive coordinator. The league knows what he deals with, having Jerry hovering over his every move and grasping at every microphone. I'd bet the Giants would be VERY interested in him after Coughlin.
But now you're just bashing Jerry and we can't have that here. I have no doubt JG could do well somewhere else. Especially after learning on the job here. It's like Romo. Put Romo on another team and he's probably going for his 2nd Super Bowl.
