Someday, perhaps when he's retired and no longer patrolling NBA courts, Joey Crawford will probably calm the hell down and stop being such a dick. Today is not that day.
During a Cavaliers-76ers game, Crawford noticed a wet spot on the court that needed some moppin'. So he called over the mop boy and told him to get to work. Only the mop boy didn't move as quickly or mop as well as Crawford would have liked, so Joey decided to give the whippersnapper a little of the ol' business.
Keep your head up, mop boy. Tim Duncan will probably buy you a beer the next time the Spurs are in town.
