> The problem is that most schools don't do that, would likely argue they don't have time to do that, and also probably spend a fair amount of resources and time on relatively ineffective bullying prevention.

Most schools just care more about their sports teams are doing, so they'd have no interest in a punishment that involved removing a player who otherwise was good enough to make the cut. Look at how many people looked the other way for stuff way worse than bullying at Penn State.
