^^I am not convinced of that.... I'd say based on his prior performances to that fight, Hughes, Serra, he seemed to do what he had to do in order to end the fight when he got the opportunity. I noticed that in the Fitch fight, he had him hurt pretty bad and seemed like the opportunity was there, but he didn't dedicate himself all the way for the finish like he did in the Hughes / Serra fight.
I agree. He was particularly ruthless against Serra in the rematch. Those knees hurt just watching em.
