Horn goes off, try missed then two in fracas. They are bench personnel. They each get flagrant Ts for fighting and are gone. Each coach gets An indirect for that. No FTs for those cause offset.

Bench players leaving bench when fight may break out. Not as clear since they are allowed to leave bench and be on court during intermission. If they don't participate in fight not sure I can toss them. Clearly if they participate they are gone.
Now, the point of rule is to limit the people around fracas. If they all run to it, and not to locker room surely violates spirit of rule. toss them all, coach gets another indirect T. If the number leaving the bench is equal no FTs. If unequal, team with less coming on near fracas gets two FTs.

I suppose I would try to figure out who all came near the fracas and toss them in this situation. I wouldn't automatically toss everyone. The kid who is on the floor but not real close (it is an intermission) doesn't deserve to be tossed, imo. It would probably be impossible to figure out everybody that's near the fight. Pick out the obvious if you can and move on. Coaches get another indirect T and if one team has more bad guys at fracas other gets two FTs. If I knew there were some innocent kids but coujdnt determine the bad ones I'd do what Adam said. I'd want to be sure before tossing. Fights are bad....

Ps. I think that is how to administer. As I think more..if they don't participate I'm likely to let them all stay because of the intermission factor. Hope I never have to decide...
