Technical on Coach with ball in flight

[Loudwhistle2]

Second half, GV, visiting team puts up a 10' jumper, just as visiting coach says to center official, "you suck" Official T's up coach, then the ball goes throught the basket. (first time for me, with a T during a shot made good) didn't count basket, coach went and sat down. I'm pretty sure this is right in not counting the basket due to the whistle killing the ball and it was not an airborne shooter situation. If I'm reading 6-7 correclty I believe this was correct. Timeline of event: shot goes up, "you suck", whistle for T, ball goes through basket. Correct?
