Our team experienced this twice this year. The first time a few players attended an amusement park. The next day the ones that attended the park were dead tired and also managed to get one of our players hurt and we lost our 8:00 A.M. game which dropped us into the "losers" bracket. Killed the tourney for us. The next time several girls stayed up late the night before our 8:00 A.M. game and.... You guessed it, we lost which sent us into the loser's bracket. I'm sure there are responsible players out there, but it is obvious that our team has few of them and a coach to go with.
