OK, I will try to work on reducing my T count.
No, take every situation and evaluate the reason why he gave a technical foul. After the next time you work with him (or now if you remember) come back and tell us a specific situation that happened.
I believe there aren't enough technical fouls called in high school games. Almost every place I've worked, there could be at least one legitimate reason to call a technical. I will be interested to hear what he is calling technicals for.
