You usually see it on extra points and field goals. Defensive players would jump on top of D-linemen's back or players in the pile to block kicks. This is a safety issue. Most states are re-charging officials into calling these types of penalties.
Is there a new HS rule that when a team misses a FG attempt inside the 20, the ball is spotted on the 20 rather than where the FG was attempted?
Is a personal foul on the defense an automatic 1st down? I thought I saw a situation where it was 3rd & 20, the foul was called and it was marked off to 3rd & 5
Hohumming- yes, hurdling penalty occurs when a ball carrier jumps over a defender making an attempt to make a tackle.
Part 1: It sounds like it was late but did they get the call right in the end? That's all that officials strive for. Sometimes it might not look pretty but it's the end result that counts. I don't believe there is anything officially wrong with throwing the flag that late other than it doesn't look too great.
Part 2: Again, I'm not a rules expert but I don't believe there is anything wrong with this unless the linemen had already gone into their stance, or the center had already touched the ball, or it was a delay of game. Again, I'd have to know the exact scenario and if that is in the rules I've never heard of it. Someone better with the rules please correct me if I'm wrong.
Is there a horse collar call in HS ? ALSO ARE THERE 2 types of Facemask penalties or just 1 ?
Part 2, Canisius broke the huddle, came towards the line and then rehuddled. I believe the center touched the ball, but I can't be positive. I'm thinking the center touching the ball and then reshuffling may have been the infraction?
19 seconds left in the game. Team with possession down by 3, with 2nd and goal at the 5. 10,000 screaming fans. It's not clear that a spoken warning would've been heard (isn't that why the mechanic describes a clear visual signal?).What you cite from the Gold Book is the correct mechanic. What we do not know is what kind of communication there was between the official and the player. Maybe he told him that he needed to move up and the player didn't listen and he just didn't get a chance to punch before the snap. That's a hard one to comment on without being there.

There's a picture of the play prior to the snap which shows the LJ. Note that the motion man came clear across the line before the snap; that would seem to indicate he had plenty of time to make the signal.
