The fight that didn’t happen between the Houston Rockets and the Los Angeles Clippers is the biggest story in the NBA this weekend, and it was the trash talk from an injured Austin Rivers that fueled the kerfuffle.

Matt Barnes spent three seasons with the Clippers from 2012 to 2015, a span that included the arrival of Doc Rivers in 2013 and addition of Austin Rivers in a three-team trade.

In a conversation with Ric Bucher, Barnes said that Rivers’ arrogant nature took some getting used to when the two players were teammates, and he can understand why players from other teams might want to pick a fight with the coach’s son.

“He talks a lot of trash and doesn’t really back it up. I think people are probably tired of that. …. He’s just very arrogant. You know, I know him personally, and at the beginning it kind of took a little bit to get used to. And as a teammate, you just kind of accept him for who he is and have his back as a teammate. Hearing guys talk around the league and seeing guys that had a problem with him while I was playing with him, I could see why. He carries himself like he’s a 10-time All-Star, and he’s not that. That kind of arrogance rubs people the wrong way.”

Barnes also had some harsh criticism for Doc Rivers, who Barnes believes is a key factor in the “demise of the Clippers.”
