I just think coaching trees are overrated. It's not some defense of Tomlin in anyway. He's gone, it would be wonderful to stop talking about him. But back to coaching trees, any coach who gets hired has had mentors along the way, but has to be his own man. If they aren't, they aren't successful. I think that is what you see with the coaches who have been under Belechick. They tried to be too much like him, and it didn't work. The Steelers had a guy before Noll...Bill Austin, who coached under Lombardi. Apparently, according to the book, "Three Bricks Shy of a Load," he tried to be Lombardi, and it was a big failure.
So if having to be your own man is a truth, which it seems to be, isn't where the coach came from somewhat diminished in importance?
