I respetfully disagree:
1.) It would feel like piling on the good people who are at PSU. Yes, they are there and I trust they will remain long after the dross is cleared out. It will be good for everyone if PSU can get its act together. SU should support them. Otherwise, it smacks of punishing the child for the crimes of the parent.
2.) How far do you want to go with morality-in-scheduling? I understand the argument that SU should act because it's a hideous, once-in-a-lifetime scandal. Then, what about murder w/ attempted cover-up? What about rape w/ attempted cover-up? Is there a line? Where do you draw it?
3.) You seem like a reasonable person. I would trust you to use a reasonable standard for applying moral rules. But what happens when less reasonable people and schools do the same. I'm not sure we want to go down this road.
4.) Don't we have the courts and the NCAA for situation like this? Does SU really need to step in? I could see a very strong case for cutting off the series if the NCAA and courts exonoerated PSU. Doubt that's going to happen, though.
5.) I think SU would seem sanctimonious. If PSU is forever defined by this one event (and it will be for a generation), then we need to accept that SU can be defined by one event too... which means SU has a lifetime cheat running the hoops program. I agree with people who say that NCAA violations are small change compared to this. Doesn't mean there will not be blowback, however.
This reminds me of the 1980 and 1984 Olympic boycotts. They hurt the athletes as much as anyone and set off a tit-for-tat that probably didn't matter in the grand scheme.
