I don't know, aside from obviously being a scary nutcase he showed a lot of promise and no major chinks in the armour to me. Beating Tua and Byrd when they were both undefeated is very impressive for a 24 year old man without much of a learning curve before that point. As grey said both were limited but they couldn't have been more different either, Ike obviously had some depth to him. I thought he could have made the Tua fight wider and quite a bit easier on himself to, maybe he didn't have the poise to box under a lot of pressure though who knows. Bottom line is he was crazy and wasn't going to avoid prison much longer than he did.
