This is a huge shock to me. He's never had any off-field incidents before. But we have seen flashes of his temper, so I guess it shouldn't be that big of a surprise. If you'd haul off and punch your coach at halftime of a playoff game, you probably have anger management problems.

Unfortunate to see. Hope he gets it together. No excuses for headbutting, hitting, slapping, a woman. Apparently in this case he headbutt her and busted her head open. Pathetic.
