He is never mentioned for this but my personal favorite has to be Mike McCallum. He had a very good awareness of his opponent's body and of his own. As though he had a total understanding of both. As a result he was virtually impossible to hit. Even more impressive when you consider that he mostly stood directly in front of his opponent. He is a must for young fighters to watch. He is standing right in front of you but why cant you hit him? theres a big lesson to be learned there.
