Because he's a self centered a**hat who NEVER takes blame for anything. It's always someone ELSE who is at fault. And he worked with Manning, Warner and Tom fricken Brady......and calls himself a QB Whisperer.
He won a game in Seattle on a missed field goal by Walsh, and acted like it was him alone who won a game.
He got OWNED in his own stadium, yet had to tell everyone how he liked being at "home" in Seattle.
All while ignoring the fact that he couldn't beat the Hawks at home in Arizona.
He's a good not great coach. VERY overrated.
