I really like how they have his peers talk about what he was like.
Also aside from being a great player, I think he is a really interesting psychological character. He is that rare person that seems to truly not care what other people think of him.
I think he is one of the most interesting players ever in the NBA. Others I would put in that category are Dennis Rodman, Bill Russell .... who else would you nominate as interesting aside from their athletic accomplishments?
