"I don't know what that means." (LGP)

[bainsey]

Coach A verbalizes loudly for a foul on B-1.

Me: "The defender had LGP all the way, Coach."
Coach: "I don't know what that means!"

Okay, granted, this was a middle school game. Still, shouldn't all coaches know a valuable rule concept like LGP? Or, am I talking too much in ref-speak? Or, is there something that could be done to teach this concept, so we can all get on the same plane?

I don't care for broad-brush statements like, "Coaches don't know the rules." In truth, some know more than others. Still, shouldn't the knowledge of LGP in the coaching ranks be as universal as that of travelling and double dribble?
