UFC fighter Chael Sonnen, never at a loss to try to draw attention to himself, appeared on "Jim Rome on Showtime" on Wednesday night, and decided to call out LeBron James and the NBA Finals.

"I think LeBron's a dork," James said. "I don't understand this whole thing. It frustrates me to hear that these guys are world champions. He won one world championship, and it was in the Olympic Games. It's so aggravating to hear a title be called a world championship when it's only done in America. If it's not a global event where the whole world can participate, you didn't win a world title. You won a national title."

Pretty big talk for someone who lost his last two fights.
