I know there were rumors years ago but wouldnt it be awesome if in the next series of TUF they had mariusz pudzianowski. He is a 4th degree black belt in karate and he used to be a pro boxer!! He also plays rugby of a weekend so his cardio should be good. Most fighters actually do the strongman kind of training so i think he could really be a contender. As long as he gets good technical advice. I think that Mariusz is such an athlete he could turn his hand to mma.
Imagine Mariusz vs Brock!!!!
