Your all missing the point. JJ loves Peyton so much he may get the hell out of the way (for the most part) and let him run the team. JJ aint getting any younger. There is no way in my opinion this team wins with McCarthy. It needs a new face. Someone who can coach, run an offense and get the most out of the QB. It isn't that hard.
When your O coordinator couldn't make adjustments to what defenses were doing, and your head coach couldn't adjust to penalties, for an entire season, you tell me if this team is going to win with less talent next year? The minute MM agreed to let KM stay as o coordinator he proved himself to be another puppet.
NFL coaching means everything. Yeah it may not work out with Peyton. But I'm jumping at that if it costs me a first. Its worth the risk to not be a joke every season. To finally maybe be taken seriously..
