Disconcertion from bench

[bas2456]

This happened during the game before mine in a tournament I was at today.

Team A is shooting free throws in the second half. Every time A shoots, bench personnel from Team B gives a friendly reminder to her teammates to "box out and rebound". Thing is, every time, they yell this as A is releasing the shot.

A made most of the free throws I saw while this was going on, so it probably didn't matter much anyways, but I'll take a stab at what could be done, and you all can correct me if I'm wrong.

Based on similar plays from the case book, it's in the official's judgement whether or not the thrower was disconcerted. If she was, then I should award a substitute throw to A, and politely tell B's bench to shut up. Hopefully that would be enough. But what if it isn't?

I'm assuming you would proceed with a T on bench personnel?

What say you? There's a good chance I will be on one of Team B's games later in the tournament, and I'd like to be prepared.
