The part I loved best was them spot lighting Kellen Moore for not snapping his chinstrap.
The R in this game knew this was his tendency, and intended to correct that tendency. In that same game, there were some plays that he, indeed, did have it snapped. Having observed that early in the game, the R believed this was no longer a problem, and didn't focus further on it. This is a case of the R having enough to do to not notice something that is not readily visible to him, even between plays; "out of sight - out of mind," so to speak. He's been able to get away with this for his entire career because it is always (quite deliberately) the lower right strap (opposite his throwing arm), and is completely concealed from view by the R while the ball is in play, and, for the most part, even between plays. He rarely runs with the ball, such that the R might see it while he is running.
Had the R noticed the strap not snapped while the ball was in play, he would have reminded the player to snap it.
As for the unusual formation, to their head coach's credit, he advised the crew of that formation before the game (a bit unusual for him), and they were prepared for it. However, I dare say the crew would have not had an issue with it had they not been notified.
