Rob Parker probably won't have Rick Barry as a radio guest anytime soon.
Parker, best known for being fired from ESPN, is now on the FS1 train and stirring the pot out west. Barry, being a former NBA player, was asked on the show to give an opinion of LeBron James' decision to dish the ball out to Kyle Korver instead of taking one of the final shots himself in Game 3. The Cavaliers ended up losing that game, but it's nothing compared to Barry going off on Parker and calling him a "loser" for asking such a ridiculous question in his opinion.
You can never say Barry isn't passionate about the game (or going off on radio hosts).
