Brock Lesnar vs Fedor Emelianenko - Why Brock Would Win

Its interesting to watch Brock's reaction's in that fight. Even when in the pocket with either Cain or Carwin, when throwing a punch and expecting a shot back he automatically turns his head away from his opponent. Thats an elementry and rookie mistake in boxing. This lets me know that A) he has done no sparring whatsoever, or B) he doesn't like to be hit at all.
Im inclined to go with the former as Brock's level of CV is pretty average. He was visibly spent vs Cain and couldn't keep up with the pace that Cain set or with the speed that he came out of the blocks with.
