Flex reached his potential believe me, he maybe could have trained harder but he took everything else to the limit and beyond, it did cost him a kidney, Cormier pretty well much the same, didnt matter whether he partied or behaved he maxed out around the 245lb any heavier and he would hold water, didnt much matter if he was in the gym or nightclubbing during the prep, so you could say he got to his potential as well.
