This guy is a straight up beast, if he improves his cardio he could seriously be top 5 in my opinion. In the current UFC top ten I think that he beats Mir, Hunt, Overeem, Barnett, Browne and possibly Bigfoot and Big Country. He would have trouble certainly with Cain, Werdum, and Stipe, and JDS. Because they are all younger, more athletic and have better cardio. Hope he goes far in the heavyweight division.
