I don't believe Dirks and Chamberlains BP numbers. Dirk moves very well for a guy his height, but he's never been a great athlete. Chamberlain was a great athlete for his days, but 525 is a little too much. Having long arms like Wilt and Dirk makes it hard having a good bench, too. Just look at Durant...
I believe Kobes, Shaqs and Earl Boykins numbers. Kobe is a great jump & run athelete, so he might be strong, too. Shaq, in his early days, was faster and stronger than most Centers.
