There has been lots of talk this week about Richard Sherman’s wild rant on national television Sunday night. Sherman, a defensive player for the Seattle Seahawks, had just caused a game-saving interception in the NFC championship game with San Francisco when a Fox Sports reporter put a microphone in his face. Sherman proceeded to call 49ers player Michael Crabtree a “sorry receiver.” He boasted that he (Sherman) was the “best corner in the game.” He yelled to the camera that no one should ever talk about him. He was defiant. He glared. And then he stormed off.
