I would be happy if you had to turn a roster in 1 month prior to HoCo. From that point you lock the roster and do check ins.
As far as the tournaments you should have to play with the players you selected in August. Players work to hard to be replaced at tournament time with other kids.
Everyone calls themselves coaches. We'll coaches build and pick the team in August. It's their job to develop the players they took. Not get scared that they are going to lose because they didn't coach the boys up over the course of the year. |
