Summary: Referee Pete Morelli gets the call for Saturday's game. He was the referee for the Patriots-Texans game on Dec. 1 when the Patriots weren't called for a penalty (the Texans had 2). Overall, Morelli's crew was known for throwing among the fewest number of flags this year, but one thing to keep in mind is that this isn't his complete crew. Two of the six other officials were part of Morelli's crew during the regular season -- line judge Carl Johnson and field judge John Lucivansky. But the umpire is Garth DeFelice of Clete Blakeman's crew, and he was a central figure in reversing the initial end-zone penalty for pass interference on Rob Gronkowski at the end of the loss to the Panthers. Head linesman Wayne Mackie, for example, is part of Gene Steratore's crew. So this dynamic takes away some of the "scouting" teams might do of specific refereeing crews.
