He went off on a trainer for not taping up his shoe because he does kickoffs. An asst coach stepped in and told him to knock it off or run sprints. He cussed at the coach and threw water bottles around and walked off. His mother brought him back to talk with the HC and the HC told him if he wanted to come back he needed to run 55 sprints, the number of plays he missed. He went off on the HC in front of his mother and started cussing. The HC told him to leave and he was off the team. Apparently his mother came back to talk with the head coach after practice and he said he might talk with the team today about Liner's future with the team. This from an AU board and now on UA boards. The poster said he had a kid on the team and was at practice I think is what he said.
But as a parent feel for the mother as he may be blowing his best opportunity ever.
