If, for whatever reason, the officials do have to stick around longer than normal, then I can definitely see the coach(es), players, fans, etc. approaching the officials despite a victory.
It would take QUITE a lot to give a T at this point (despite the provision being in the rules). I think the easier and more professional route would be to simply write up the team for these actions and let the school board deal with it.
Think about what reaction you'd have in the overtime period if the coach did bring his players back onto the court. Team A now thinks that they're screwed and legit fouls are going to be questioned, more T's follow, etc.
That being said, I have a feeling that this coach and team won't be going up to officials after games anymore!!!
(I kinda wanna T up a team now after a game just for the cajones factor! hehe...
