But that is what Dana White actually likes. When obvious underdog beats dominant fighter (like Edwards was receiving beating during all fight, and finished Usman with a single high kick), Dana always say that "that is what UFC is about". You never know what will happen, you never know how fight will go, as in octagon anything can happen.
Luck plays a huge role in MMA, it's not only about skills.
Conor McGregor's 13-Second KO of Jose Aldo is a great example of how luck matters. I know they are both skilled but Jose could really beat McGregor. I think even the Jon Jones can be beaten by underdog if luck strikes. But maybe this is really a very bald statement.
If UFC was about getting maximum milk from their cow, we would see Conor, and p4p fighters fight every weekend. And UFC perfectly knows how to hype a guy. Just that Paddy the fatty that came out of nowhere. Average fighter. UFC made his metabolism as a feature and we see everywhere Fatty drowning in fast food and later fighting slim in octagon.
It doesn't work like that in UFC. While we see football matches one or two times a week, if fighters were to fight every week, people won't be interested in them. It's the rarity of their fights that make people hyped up.
