During a recent talk with MMA Fanhouse, Top Rank's Bob Arum unloaded some big shots at the UFC and Mixed Martial Arts. Arum's recent comments land on the eve of UFC president Dana White's recent negative comments about boxing and the Floyd Mayweather-Juan Manuel Marquez pay-per-view.

"I've been to an MMA fight night and it's terrible. I admire Dana White and all the UFC guys as they've done very well. But for me it's junk, it's garbage. You've got guys rolling around on the ground and it's not a sport that shows great, great talent. The guys can't throw punches to save their ass and when a punch lands they've got no chin. They're not like boxers and aren't trained like them," Arum said.

Arum says the UFC audience and the boxing audience are entirely different. His characterization of the UFC audience and the UFC fighters are off by a mile. Instead of watching a UFC event, Arum must have been watching the movie American History X.

"I look at the UFC audience and boxing audience as entirely different. Boxing's audience is largely ethnic and includes the hardcore fans who, like me, can't watch UFC. UFC's a bunch of skinhead white guys watching a bunch of people in the ring who also look like skinhead white guys. Ninety per cent of the MMA audience have tattoos — and I don't care because that's up to them," Arum said.

"But they aren't people who will have any interest in boxing. The only guy they might want to see is Kelly Pavlik. For me, and people like me, MMA is not something that they ever cared to see. It's horrible."

He won't deny the UFC's drawing power and their ability to market, sell and promote their events.

"They've made us adapt as they do an unbelievable job in certain aspects — and we're trying to duplicate that. They're sensational promoters and are class guys who have built a good business. But I think the majority of my generation agree that it's junk," Arum said.
