I sat through a freshman football game yesterday where false start was called 6 times in a row, both teams at fault. Then one clean play, then false start, then clean play, then 3 more false starts. Both coaches yelling, fans booing, 1H momentum killed. No FSs called in the 2H, and not because they didn’t happen.
Going to call BS here for a moment. First you are talking about HS players. If a team is that poorly coached, then I would be booing also. Second, 6 false starts in a row cannot happen against both teams, only the offense can commit a false start. The coaches, hopefully WERE yelling, at the players to remember the snap count. Again, if there were false starts committed in the second half that weren't flagged, you are putting the other team at a disadvantage. Sounds like you might want umpires to start picking winners and losers.
