Having trouble getting through all of the posts in this thread, but I don't think that anybody has raised these (at least potential) issues that extend beyond concern for the students health and who to blame:
1) Having this happen right before signing day is not a positive for recruiting (parents could be alarmed, for one thing). It strikes me as having a chilling effect similar to learning that a hospital is having a problem with staph/MRCA.
2) If you Google this stuff in the past, there have been lawsuits brought by students, so there is a potential hit for the university (which would also keep it in the news at each court date/event). Not good. The PR is probably much worse than any financial settlements. An Iowa student got awarded a whopping $13,500 after all of the hassle. (As long as the university took prompt action to get them hospital care their negligence exposure is probably limited).
3) The way Scott Frost took full responsibility (and worded things, in his FULL COMMENTS)
should make this a minimal issue, as long as the two points above don't become a distraction/issue. I have the feeling that the way Bill Moos handles this with the families affected (some of which may never make the news) could be a factor. Since Oregon has dealt with this and Moos (as a former Oregon Athletic Director and WSU AD during the Oregon incident), he may have some knowledge of how they handled their cases from Jan. 2017.
Finally, some interesting reading (YMMV) for you from a High School incident in Oregon:

IF this can be "spun" as a sign of the poor conditioning of the team under Riley's regime (rightly or wrongly) there should be minimal affect on the SF regime, but it IS a bad sign if that is indeed the problem. If Duval has "done this 5 times in the past" and this is the first time he has run into such poor conditioning issues, it is a sign of how far the Huskers have fallen and you may need to adjust your recovery timeline accordingly.
