Duke @ Notre Dame Plays (Video)

[Freddy]

Re. the first video. This is especially applicable on the high school level. Those working on and assessing those on the NCAA level may have differing opinions.
When an official's first impulsive movement in immediate reaction to a play like this is two fists rising from the hips, there's only one call that's gonna result. Most who start with two fists rising default to a block because of the early initiation of what will become the later fist-banging-on-the-hips signal, regardless whether it was actually a charge or not.
At least on the high school level, that seems to be true.
Further reason why to insist upon the approved mechanic of a single fist in the air first, then go to the foul signal.
Anybody else find this is true?

(Come to think about it, JD Collins insisted upon that very same thing to his NCAA-M officials this preseason, didn't he?)
