Just an outstanding job by the 5A crew. Two things stuck out to me:
The way they handled the intentional grounding call should be made into a clinic video. The Referee held the spot of the pass. The wing official came in to communicate that the pass did not make it to the neutral zone. The Umpire confirmed there was not an eligible in the area. The R then dropped the flag. Textbook.
The unfortunate kerfuffle on the DC bench area following the interception at the end of the game could have been much, much worse. But the crew acted quickly, assisted by the coaches, to isolate the two trouble spots, and then moved in to shut them down. Great job by veteran officials who did not get rattled by the situation.
