So again, I ask you, what did you want Nelson to do? Give up a completely dominant position? I'm baffled by your train of thought here.
Did you want Dean to stand them up? That would have been completely unfair, considering Kimbo was doing nothing to improve his position, and Nelson was throwing blow after blow to his skull. Even if they got stood up, Nelson would have taken him right down again and did the same thing.
This fight was just utter and complete domination, I dont see how anyone could see it different or knock Nelson's performance.
