I think Kimbo had potential, going toe to toe with Sean Gannon..a regional level pro mma fighter, judo black belt and golden gloves boxer for 15 minutes is pretty impressive for a guy with no real formal training. He wasn't going to be a world beater but I think he done a LOT better than what people gave him credit for. Close and competitive fights with a few good vets, I think his at a weird position where he is too big to make LHW, but too small for a HW....his cardio has always been horrible but considering he went from chain smoking 260lb+ steroided bare knuckle backyard boxer to professional mma fighter within a few years I can see why.
Perhaps if he got into the sport a bit earlier, with his athletic background & boxing he might of been able to have a half decent career, but everything worked out pretty well for him...hasn't got the most impressive victories but he has made a huge name for himself and made a fuckload of money. His last fight was pretty pathetic, I don't know why he gassed so hard I think he is a lot more capable then that even at his age, especially considering he was training at ATT with high level coaching staff....makes my head scratch.
