I mean if the coach was hot...........
I work with some coaches who are "touchy feely". Put a hand on your shoulder etc. I address them politely and ask them not to do that, and haven't had a problem with it. I had one coach try to whack me in the butt after I made a call against his team (He also said Good Call) and hit me RIGHT in my scar. OUCH. I asked him not to do it again!!
As it sounds here, this was a coach just being an ***. It is unfortunate that his actions would cost his team the game. Assuming the other team made their free throws!!! Not that I would put money on him being on the bench to witness them!!!
