Combination of poor matchmaking and too expensive.
How is a casual sports fan supposed to follow the sport when most fights are PPV?
I mean I can understand putting the huge events on PPV like the Tyson-Lewis or your ODLH-Tito, but when you got fights like Rahman - Barrett on PPV, something is damn wrong.
The casual fan is NOT gonna drop $50 to see these guys fight.
So they don't pay, they can't follow. And if they aren't following, they're not gonna pay. Catch-22.
