Cormier has been basically perfect, winning essentially every minute of every round. But so many of those wins came against old opponents: Old Henderson Old Barnett Old Frank Mir Those wins were all nice, so was Bigfoot Silva, so was Roy Nelson, but its hard to favor Cormier over Fedor.
It's hard to favor anybody over a Prime Fedor. Even an old, fat, unmotivated Fedor was basically winning the fights or competitive in the fights that he lost. Werdum - Had Werdum on the ground and had top position when caught in triangle Henderson - Was beating the **** out of Henderson, when caught with that shot from behind after getting sloppy Silva - I believe the last round of Fedor/Silva ended with Fedor attempting a submission, then the fight was stopped between rounds.
