The Harbaughs are using teams built by their predecessors. Belichik isn't going on the market until Brady retires. I don't agree about Tomlin or Carrol. Cowher is a great coach, but high power passing offenes are what's hot and Sean knows it as good or better than anyone. Let me ask, how many of those coaches would have been able to come in in 2006 and build a team that won a Superbowl? Belichik is the only one I would go out on that limb for.
