I was thinking about the reasons Dennis Allen isn't working out, and I think I've solved the puzzle. There is a formula for having a successful NFL (or even college) head coach.


If you are a defensive head coach, you need to have very special leadership abilities to earn your team's buy-in and keep it. If you are an offensive head coach that calls the plays or has a very strong influence on the offensive gameplan/playcalling, and you are adept at it, the bar seems to be lower....
