Nobody is comparing him to Fedor as a fighter- The point is that at his weight class, he is as or more dominant than Fedor is at heavyweight right now. Overall, obviously Fedor is 110% more dominant and acomplished.
But for anyone that saw the fight last night, he made Rashad look like an absolute chump. And thats not taking anything away from Rashad- He was in shape, he looked prepared, but he just couldn't compete.
