Before his handshake with Ravens Coach John Harbaugh, Belichick angrily pursued one of the officials and grabbed him by the arm while berating him. The NFL does not allow contact with officials -- the Ravens were penalized earlier in the game when Harbaugh bumped one while attempting to call a time out.
"I can't believe Bill Belichick just did that," NBC commentator Cris Collinsworth said during the "Sunday Night Football" broadcast.
Perhaps Belichick was angered by the pass interference call that set up Baltimore's game-winning field goal. Or maybe it was the fact that the game-winning field goal, which soared above the right upright and appeared very close to being no good, was not reviewed (a lot of people were upset by that, but it turns out that field goals are not reviewable).
Or it could have been one of many questionable calls or noncalls throughout the game, which was a rematch of last season's AFC championship.
“I'm not going to comment on that,” Belichick said. “You saw the game. What did we have, 30 penalties called in that game?”
Actually, there were 24 flags thrown, 10 against the Patriots. Regardless, Belichick can rest assured that the league will have something to say to him about it -- and that his wallet may be a bit lighter afterward.
