more high level athletes than would would expect are absolute party animals, alcoholics, drug and sex addicts. they get by on natural talent and Tuivasa has a ton of it whether you like to admit it or not. he just has glaring technical weaknesses in his mma arsenal that he seemingly has never bother to address. and if I recall wasn't his fight against Gane for the interim title? so just on natural talent alone he was fighting for the interim heavyweight title.
like it or not, most human beings could not even come close to doing what he did on just natural talent alone.
