After he beat Mir, a lot of guys thought he had come back as a changed man. Now he was conserving himself... He tried to conserve himself against both Bigfoot and Werdum. He still ran out of gas against Bigfoot. He was REALLY trying to keep things moving slowly in that fight. A lot of fans think that Werdum was showing his standup too much respect, there are reports of Werdum hurting his knee, and perhaps Werdum could have pulled off a fight altering late flurry. After the Bigfoot fight, that's why he attacked Browne the way he did. And that strategy failed too, because he almost finished and then became a sitting duck. (funny enough, I think EconoReem would have done better against Browne and 2 Minute Reem could possibly TKO Bigfoot Silva). I think he just needs to pick one or the other (based on the opponent), commit to it 100%, and the HW belt could become his.
