Theoretically at least if you left with a coaching change but a quick turnover happened? I.E. Mr. High Octane leaves quick, a kid transfers then may want to come back maybe if easier to obtain degree due to credits etc. This reminded me since I saw this tidbit. I know Pitt will not be it but wonder if he will try D1 again.
