1. False start, all 11 players never set for one second.
2. The ball is dead when a loose ball touches something other than a player, an official, or the equipment of a player or official.
3. A coach interfering with a live ball falls under the unfair acts article. Assess whatever you think is equitable. In my opinion, that ball was moving pretty fast and was clearly going out of bounds and nobody was going to recover it. My penalty would be to place the ball where I think the ball would have gone out. It still counts as that coach’s first UNS, but he obviously wasn’t trying to interfere with a recovery and I don’t think there’s anything here that merits doing anything more than “making it right”.
