In Painter's defense, he has played very well lately. He is getting no help.
The coaching of this team was exposed long before last year's playoff loss. Try the Super Bowl against New Orleans. People have been calling for Caldwell's head since then (and to a lesser extent, Polian) but the cries are increasing. Polian's recent drafting ineptitude has caught up to the Colts and placed them into a situation where the holes that needed to be filled weren't filled and the depth Polian thought he was building never happened. My god, Donald Brown and Jerry Hughes (2 recent #1 picks) are third or fourth string now. They're that bad!
The fact is, Peyton covered all these issues. No other QB in the league today and maybe none in history could carry a team like he can. If he would've had a good defense surrounding him for most of his career, they would've won 2 or 3 more Super Bowls -- I have no doubt of that.
Brady can, no knock on Peyton, he's awesome but essentially the Pat's 25th ranked D last season should have netted them a 8-8 record not 14-2. Come playoff time last two seasons that got exposed, with zero pass rush and quality D's keeping Brady and the O of the field a lot and below 20 points they lost both times..
