I will always question Vitor. I have never seen him really come out hard for a third round. he threw away his fight with tito because he was gassed or discouraged. it was a close fight, but he threw that third round away. he has been reduced to the guard-pulling butt-scooting vitor in a few of his losses, in which he was clearly broken (or discouraged)... against saku, overeem, and bones.
in the first round, he's the best in the world (overeem fights this way, but I thought vitor took it to overeem pretty well in their first rounds). once he gets hit to the body a few times and actually has to dig deep, that well is pretty shallow. the one time I've seen him go for it in the third was against chuck.... he got caught and chuck stole the fight. but in most cases (hendo, tito, overeem, saku, etc.), he's pretty much checked out by round 2
*** also, heath herring beat him. the judges favored vitor because he was smaller but he lost that fight. one of the most overlooked robberies in mma
