I think Fedor is overrated currently but he is still far superior to Werdum. That's how the sport of fighting is, if two guys fight enough times eventually the lesser guy will win and during that fight Werdum's number was pulled.
I think Fedor over-estimated how hurt Werdum was and got way too aggressive in his guard. He should have let Werdum stand up so he could knock him the F out.
They'll have a rematch, and yes, Fedor will win that one for sure.
