I always liked Big Red. Even when he joined the Celtics late in his career, I didn't hate him for it as I would most ballers.
I liked him because he was a hippy athlete, a rarity. Of course his long hair didn't last long in the NBA. Not that there was any rule against it, But when he would try to post up, wily veteran bigs would get up tight against his back so the refs couldn't see them grab a hold of his ponytail. He could barely move.
