fonzzy, Good call. It's one thing to let a "little" travel go, it's quite another to let a play go that purposefully (if ignorantly) breaks the rules. This coach was teaching the girls to do something that's illegal. That's got to be called.

Would I make this call in my partner's area? No. That said, your league assigner on this apparently wants you doing this for rookies. While I don't necessarily agree with this philosophy, it is what it is. You're doing fine if that's what he wants you to do.

Now, on to your original question. Was there a game/site manager present to help you with this? If so, get him/her involved and tell them this individual needs to be escorted from the gymnasium. Your other option is (if the time frame is reasonable, I can't quite tell from the OP) to issue him a flagrant T. The comments he made to you would have been a flagrant T in the middle of a game, and the final horn does not end your jurisdiction.

After re-reading the OP, it sounds like not much time had elapsed from the final horn. In a HS game, you'd have been off the court. However, since you hadn't left, you still had jurisdiction for a T. Don't be afraid to use it; and if you do it, make it flagrant.
