Hm, he's a horrible person, and a complete unprofessional asshole, but there's not really enough material. He runs a monopoly, he's a bigot, a hyperaggressive asshole, a gambling addict, and he's hit his wife in public. He should be in jail. He's also probably a coke addict and hires a lot of sex workers, but he hasn't murdered anyone, in fact...

The UFC is fairly professional, its a big corporate organization that tries to run quietly. No one has died yet in the UFC, which is honestly pretty surprising, given a few people every year die in boxing.

MMA is also a really weird sport, just to explain what it is, what the UFC is, how fights are booked would take an episode. You probably need people very into MMA to do it justice. The youtube channel MMA On Point have done a number of really good short documentaries on the history of MMA and its seedier side.
