obviously he said it required a lot of stamina....so does mma. its not the stamina that got kimbo its his knees hurting like ****...
No? He was gassed in the first round. He basically 'gave up' when he realized he wasn't going to be able to punch the guy once and knock him out and the guy was actually going to fight back.
bah tyson was the same way....if he could get you in the first few rounds you were done. Knockout power etc. If you could make it through his barrage till the later rounds he was gassed.
