What's the call?

Therefore, the only call that is supported by the rules here is the TEAM technical foul for having more than five team members participating.

Actually, I do know. I watched #21 leave the court and sit down on the bench. As I put the ball in play, I was on the endline opposite the bench. When I heard the coach asking for timeout, I looked toward the bench and the coach was the only person standing. I know that #21 entered the court illegally, even though I did not actually see him do so.
