Bob Arum is one of the most well-known boxing promoters in history, but he's never learned to appreciate mixed martial arts.
The 88-year-old was asked for his opinion on the fellow combat sport Monday during Ariel Helwani's MMA Show (warning: NSFW language), and he didn't hold back.
"As far as I'm concerned, it's trash," Arum said. "I don't like it. I don't like to watch it."
Although he did credit UFC promoters for building a following, he noted he still personally doesn't like watching MMA.
"I'm not going to say that this is a sport that I love, because I don't," Arum added. "It really does nothing for me."
Helwani began the interview by reshowing a 2009 interview at Yankee Stadium, which featured a harsh breakdown of MMA from Arum:
"For me, MMA is garbage and junk," he said.
Arum also referred to UFC fans as "skinheads" and said the fighters were "guys rolling around like homosexuals."
It seems the last decade has not changed his opinion on the sport.
Arum is a member of the International Boxing Hall of Fame with a career that began in the 1960s with Muhammad Ali. He founded the promotion Top Rank and has helped organize fights for some of the biggest superstars in the last 50 years, including Sugar Ray Leonard, Oscar de la Hoya, Floyd Mayweather and Manny Pacquiao.
