According to NCAA rules, "
Section 10. Penalty for Unsportsmanlike Conduct of Bench
Personnel
Art. 1. The penalty for a direct technical foul involving unsportsmanlike
conduct of bench personnel shall be two free throws to a player of
the offended team. The ball shall be put back in play at the point of
interruption."
You would shoot all T's before the 2 shot foul. SO you would shoot the 4 free throws with the lane cleared then fill the lane to shoot the personal foul free throws, this is the POI.
What to do if your partners don't want to hear your information....My suggestion would be to say, "I'm 150 percent sure that @ the college level we shoot the T's first then go to POI." If they still don't agree then it would be your resonsibilty to bring this back up in the post game , if you have one. Which it's sounds like your partners wouldn't care to do. Bring out the rule book and discuss the rule. If you still don't get nowhere then leave and report the infraction to you Supervisor.
