Hmm possibly. But wonder why Shay said he wasn’t leaving and then all of a sudden decided to enter the portal.
My guess is that he intended to stay, but something changed that caused him to change his mind. Was it a new coach? A change in scheme? A change in procedures? I have no way to know, but any time you have a coaching change, that can happen. I'm certainly not implying that there is anything wrong with the new coaches, only that they may do some things differently. When they bring in new players, I'm sure it will all work out.
This is not just an Ohio problem. With the portal, it is the new norm. Look at other schools that had significant changes to their coaching staff, and you'll find the same thing. All things considered, Ohio is far, far lower in turnover than most schools with the same amount of change to the coaching staff. It will all work out, in the end, and presuming that there aren't too many more coaching changes after this year, next year should be better.
