confused sub
 

Situation: Varsity boys, A6 and B6 have reported and are waiting to enter the game. Foul, A1 to shoot 2. After first free throw, horn sounds, I beckon the subs. B6 enters, but A6 points at A1 and says, "I'm in for the shooter."
Second free throw is good. Horn sounds. I beckon again, A6 enters, but A2 leaves, not A1. I had never seen this happen before. Is there any action to be taken here?

Nope, coach can change his mind and replace a different player.

Legal substitution.

I have a friend of mine that is a Varsity Girls coach, and one of his KEY tactics, especially for teams that like to push the pace, is to have a sub at the table at the second of every two shot free throw situation. If the shot goes, he slows down the game which allows his team time to get back on defense. If the shot misses, he puts the sub back on the bench. Through the years, I haven't seen someone use that tactic very often (maybe 2-3 teams total), but it works.

Very interesting. I've never really given that much thought. Then again, I'm not a coach, but sounds like a good tactic.

This is why I would like high school and college to adopt the NBA's rule, which allows subs ONLY before the final free throw. Your friend's tactic, while perfectly legal, is (IMO) an unfair advantage to a team that presses.

You are right. It proves to be a big advantage. I have watched him take 3 different teams in three different classifications to Regional Tournaments, so he obviously knows what he is doing.

I don't think it's unfair at all. Both teams are able to use it.
