Hmm, maybe... But part of "finally having an adult in charge" is trusting that when he inevitably makes mistakes, he will handle it well.
When Callahan made mistakes, his attitude was "you're silly morons and this is too complicated for you to understand," when Bo made mistakes he went ballistic and blamed the universe, when Riley made mistakes he said "gee whillikers, at least we had fun," and when Frost made mistakes he ignored reality and acted like he had all the answers while his brain crumbled under the pressure.
With Rhule, I've already seen and heard PLENTY from him to know that he is comfortable enough in his own skin to own up to any mistakes, and turn them into teachable moments. I think he's a very rare type of coach who is going to come across as a true leader, not just to the players but to the fans. We haven't had someone like that in a loooooooong time.
