He was no doubt a dominant player, but just imagine if he'd had a work ethic? Wilt worked out like a fiend when no one else did, Hakeem always tried to improve his game and footwork, Shaq just ate. He's a good guy, never made the headlines, but I still think of his career as underachieving. I once heard Barkley make a similar observation (about himself). Basically, he was talking about how hard he had to work to be an effective player once age, back problems, etc. started to slow him down. He then basically acknowledged that he'd been a lazy bum when he still had his full physical gifts thereby left a lot on the table.
