Z is number one, massive skills and size allowing him to over come what should have been debilitating foot injuries. Also a classy character. WorldB Free could number 2 as he carried the Cavs during their darkest days. Hot Rod is probably next with the most unselfish team game that belied his great talent.
. Wilt Chamberlain is my all time fave. Earl the Pearl Monroe comes next, especially during his Baltimore Bullet period. As number three I'll throw out that Akron legend, backboard smashing teammate of Monroe, Gus Johnson. His exploits fascinated me as a kid, he played like an uber athletic Charles Barkley.
