The greatest current coaches in American team sports all have total control of their organizations. Gregg Popovich is not just the coach of the San Antonio Spurs; he's the president of basketball. The only person with more power than Bill Belichick in the New England Patriots organization is owner Robert Kraft himself. The only person with more power than Nick Saban at Alabama is the governor of the state. Actually, nix that because there is nobody in the State of Alabama who is more powerful than Nick Saban.
