should the girls that let the teams down have a punishment other than not participating at State?
What's troublesome to me is having girls on a competition squad who (based upon your post) apparently didn't show up without a valid reason. I understand WHY they were not allowed to compete, but as someone else said, the only people punished were those who cared.
I would submit running laps or some sort of physical activity would be more appropriate. I'd also warn them that future disobedience could lead to not be allowed to try out for competition again. Punishing the many for the actions of a few isn't productive.
