After reading the ESPN.com interview, it all started to make sense to me.
Ron is having some problems at home, most likely due to the immense amount of time he's spent playing basketball and working on his album. Because of this, his family isn't happy that he's never around. As such, Ron began to ponder retirement to spend more time with his family. But due to his love for the game, he instead decided to ask Rick for some time off, to unwind and calm his family down a bit. Rick rejected his request, which irked Ron. JO went to try to talk to Ron about how much the team needs him, and the whole thing blew up into an argument/pushing match. Due to this, Rick benched Ron for two games.
Well, it makes sense to ME, anyway.
