bbcoach7, good to hear from you.
I agree with you on the guy who watches the kids after calling a foul. Early in my career, I did the same thing. Other than an outburst, I've learned to trust my partners to handle a kid who disagrees with a call.
And for what it's worth, I hate to see kids pull their shirt out on the way to the bench on their 5th foul, but I don't think it is worthy of a T as long as they aren't disputing the call. Pulling the shirt up is a different story.
I once issued a T for a kid who pulled his shirt off and threw it toward the bench. The coach came over and said, "Sorry, he saw Dennis Rodman do that and didn't know it was illegal."
