Dunk in pregame
 

There was a bjv game in our area with a interesting warmup. As the home team was warming up, a varsity member got in the line and dunked. The officials T'd the home team, gave them a team foul, and coach had to sit. What do you think?

Personally, if the varsity kid joined the JV layup line, I've got no problem with the T. Coach should keep him off the floor. If coach is in the locker room with the team, different scenario, IMO.

I think that player had extra running in his next practice.

My coach would have had us all running extra.

I'm guessing you wouldn't T him up just for coming on the floor and warming up so you're invoking the rule against dunking?
Is so, what if he'd joined the other teams lineup and dunked? Or what if he had been a random fan who ran on? And why wouldn't you make them addd him to the book (which depending on the time remaining, might get them another T).

Good questions, and the answer would like depend on the situation. I'm sure the team would object the moment an unfamiliar face got in line.

I'm not sure a T applies here.

It's been explained to us that, at halftime, if the varsity comes on the floor and shoots around while the actual teams are in the locker room, that's fine, until the actual players of that game take the floor again. Additionally, if someone dunks who's not playing in that game, we have no jurisdiction to give a technical foul.

I have to think this also applies in pre-game. Besides, this infraction (pre-game dunking) is a player technical foul, not a team technical. Granted, this player shouldn't have been on the floor in the first place, but if the player is not in the book, there's no foul.

I'm not married to the idea of a T, but I'm not going to fault an official who calls one here. Besides, as 26yg notes, there will be lessons learned this way.

But what's the rule basis here? 2-8-1?

That gives you the authority to call the T without adding to the book. I'd likely not assess the indirect in this case, and I'd have to feel certain that it was.a player from the same school, but there's a good chance I'd go there if it played out as I envision.

Unless it was a player for either team I am not assessing a T here.

Wait, what if it's a JV girls' game?

Then its a forfeit.

A technical foul is definitely WRONG in this situation.
The rule is clear and states that the act must be committed by "bench personnel, including the head coach." (10-4)

Simply have the person removed from the court and continue with the pre-game warm-up.

A T is a T is a T
 

T him. Presumably the rule in effect says no dunking in pregame. He's part of the pregame for one team if he's on the court and in uniform, per 4-24-4. He's in uniform, He dunks. We whack. The coach is responsible for controlling his own warm-up.

I find the excuse that he's not bench personnel because he is not in the book unavailing. That would mean a team could send its team out to warm up, list nobody in the book, dunk away, intimidate the opposition, then retreat immune from anything beyond a single administrative T
