I think it is far too early to guess what punishment, if any USD might get (although breaking my own rule, I can see USD punting the WCC Tournament for a couple years voluntarily, and solving the 8/9 bonus day problem. At least for the men's side).
But, as PP said, I don't see everyone staying with these problems. I can see mass transfers that will make USD struggle with little hope for years to come. If things move quickly, might the NCAA even say that players leaving won't have to sit out the normal transfer year?
