With 1.9 seconds left in overtime, the Mavericks needed their last timeout to set up a potential game-winning play.

Instead, Josh Howard called it too early, and when they ended up losing 101-100 to the Heat in Game 5 of the finals Sunday night, the Mavericks unleashed their anger.

With players storming to the locker room, team owner Mark Cuban ran onto the court and screamed at offical Joe DeRosa, then went to the scorer's table and stared down commissioner David Stern and other league officials. Cuban then went up the tunnel toward their aisle and kept screaming and staring.

Stern made his way out, but Cuban, who was wearing the jersey of suspended forward Jerry Stackhouse, didn't let up.
