When you see an accomplished coach in the NFL vehemently chasing an official demanding answers for his team's defeat, you wonder if this is what you really intended to watch. There seems to be more drama off the field.

New England Patriots head coach Bill Belichick put himself in hot water when he grabbed the arm of line judge Esteban Garza after the controversial ending of the game played against the Baltimore Ravens, which was won by the latter 31-30 Sunday. Although, he later denied disrespecting the judge, saying he was only trying to get the judge's attention to see if a review of the play was possible.

"I've coached in this league a long time and never been penalized, never had any incidents with officials or anything like that," Belichick said. "I have never meant any disrespect or in any way tried to abuse or be disrespectful to the officials and the job that they do. I'm trying to get an explanation for obviously an important call..."

But Belichick isn't the only one complaining about the calls made by the replacement referees.

Washington Redskins offensive coordinator Kyle Shanahan was flagged for unsportsmanlike conduct after his intense argument with the officials during the game against the Cincinnati Bengals Sunday.

Later on Monday, Shanahan admitted apologized for his conduct. "My emotions got the best of me, and I know it's my responsibility. This will never happen again," he said

The NFL is also looking into the conduct of Baltimore Ravens head coach John Harbaugh. He reportedly bumped an official in the fourth quarter of Sunday's game. In his defense, he later said that he was only trying to get the official's attention.
