Ball hits the coach

[Tim Roden]

If you have a coaches box, you can nail him for being out of the box. It doesn't extend onto the floor. If you are in a seatbelt state. This would be very tricky. After all a coach may rise to acknowledge a good play. But he cannot go onto the floor during a live ball. So by the book, you are correct. In this situation you have to call a T because the coach is not part of the court as an official is and he definitely interfered with play. So the call is a good one.
