Yeah makes it odd. Also maybe just blown out of proportion. If it is just Trob and his group, maybe he was ****ed with what he saw on tape. I had a coach once just leave in the middle of practice. We were all like wtf, and next day it was him trying to prove a point. His time was valuable and we were practicing like we did not want to be there so neither did he and he bounced.
I mean what could the other reasons be? disagreement with a kid? Kids not paying attention? If manny was not in the room there are only so many reasons he would walk out.
