Can’t find the language but I thought bands could not play with less than 15 seconds on play clock. When we were at the goal line their band kept blaring and holding a note as loud as they could until right before we took the snap, obviously trying to make it difficult to get plays called in and for AO to communicate to team. He had to walk up to each player and practically yell in their ear. I hadn’t seen this before, if legal seems very unsportsmanlike.
