Depends on what you're asking if you're wrong about.
Did he leave the Colts out to dry? Yes (though I don't really care for Indy, so I'm not up-in-arms about that). Was it dickish of him to not even call the Assistant Coaches that he had been assembling either before telling Indy he was not going to take the job (or call them immediately after)? It sure was. Are you right in this insistence that he hasn't learned from his mistakes, from a pure
coaching standpoint? No, there I think you're more likely to be wrong (again, I'm not speaking to his personality or anything, which I would agree that he comes off as an arrogant prick).
But I think the guy has obvious talents at coaching the offensive side of the football. You've been prattling on here and on the football forum over him in an unusually obsessive manner. I personally find it kind of fascinating. I mean I get why Denver fans are going to have a natural dislike of him, the guy came in and was an absolute train wreck of a head coach w/ roster control. Absolutely abysmal. But come on man, is it not time to just move on to the "I don't really care what that guy does, it doesn't concern me or my team" phase? Denver has seen a pretty good amount of success since he left, including a Super Bowl victory.
I mean, is he at least paying you rent for the space he clearly occupies in your head?
(I'm merely joking here, but for real--he's a non-factor to the Broncos at this point, they've moved on and have had success)
