Disconcerting action.

[rainmaker]

It seems to me it ought to depend on the level, the atmosphere, and the history. If the coach had never done it throughout the whole game, and on the last free throw, in the last five seconds he does that, it's different from a coach that yells during every free throw. If it's a varsity game in a packed gym with everyone going wild, then tough! But if it's freshmen and there are only nine fans, and there's a dead silence, and suddenly there's this weird voice, well, I guess I'd be with MTD. I've told benches to stop trying to disconcert, although I've never awarded the substitute throw. But at JV level and above, coaches ought to run at least a few practice free throws with some crowd noise and bench noise just to help kids get over it.
