I would assume he dominates his sport like no other. I know he plays tennis. Other than that, I have no idea.
I've not given up on Russell or Davis. Russell has the tools, he just needs the desire. He could get the desire. Al Davis was an innovator. Without Al Davis, the AFL died a slow death. If he still has his faculties about him and a desire to change his way of thinking, he could still do great things. I'm not sure he has either but it's possible.
