Sub-V I will warn the player in the lane or the bench. "Son (or coach) next time that's a violation." Don't recall ever going back and "getting it" later as it stops.
One time during a Wreck League game I actually said, "Alright, who's got the shooter?"
Young man said, "Me."
I said, "Good, now there's no need to talk about it anymore, right?"
They got the msg.
