after investigations and all those accused are found guilty...
all coaches who knew and did nothing: immediately fired and any compensation forfeited
all players involved (minus the victims): scholarships immediately forfeited; expelled and banned from the school and ALL future school functions (basically, be disavowed by the school)
program overall: shut down for 3-5 years and allow non-involved/innocent players to transfer without losing any eligibility.
make the punishment hurt.....BAD! make it known that if shit like this happens, the consequences will be harsh.
