Velasquez, Carwin and Lesnar, the first three guys Fedor would likely fight in the UFC, have a combined record or 21-1. Their combined competition pales in comparison to the fighters Fedor has beaten in his career. Brett Rogers win over Arlovski puts him way ahead of those three guys in WAMMA HW title contention. Throw in guys like Overeem and Barnett and it is clear that Fedor has gone where the proper top competition is fighting. And the idea of a Couture or Mir lasting more than a round versus Fedor is laughable. Both of those fights would be ridiculously lopsided. There are no other remotely compelling UFC HW matchups.
