Nothing like a good elbow to the kisser to start a coach fight. The delivery man: Denver’s JR Smith. The recipient: Antoine Wright of Dallas. Mark Cuban will be damned if he let’s an elbow to the chops go without David Stern noticing – he sent tape of the incident to David Stern’s office. And now, Cubes and George Karl are in a war of words.

“Stay away from my players, stay off the court, don’t get involved,” Karl said. “If you want to interact, interact with the league office and interact with your own players, but don’t mess with my players. There’s no room for it. If this was a normal fan, he would have been banned from the building and maybe not ever let back in the game. When the game starts, he is a fan. After the game, he’s an owner, but during the game he’s a fan.”

Who wants the unenviable task of tallying anyone Cuban has feuded with – in and out of the sports world – since becoming the Mavs’ owner? If you’d like to take the challenge, you should get done by the All-Star game.
