Another big mistake

The Ravens continue to be their own worst enemies in this game. They had the Patriots stopped on their second drive of the game, but Haloti Ngata clubbed Tom Brady in the head as he let go of the ball on a third-and-long in Ravens territory, keeping the drive alive. It was the kind of mistake that makes coach John Harbaugh lie awake at night, but it was a heat-of-the-moment situation rather than a bonehead play. What I'd like to know is what Ray Lewis was doing after the Patriots got that first down at the 1-yard line at the end of the first quarter. He made the stop to keep Sammy Morris out of the end zone and rushed out of the pile to celebrate the tackle, even though the Ravens failed to keep the Pats from getting the first down. The only thing I can figure is that he had a brain cramp and thought it was fourth and goal.
