Tony Grimes is a 5* 2021 CB who just reclassified to 2020 so he could get to school earlier and avoid being stuck in HS without a football season.
I think it was the SBTribune that had the article on Buchner and the transfer and it wasn't just so he could EE, but so he could take one semester AP classes so he could get more credit before starting college. If he wanted to, he would probably be able to be NCAA qualified to reclassify.
The real question is if he would want to. He would be using a year of eligibility where he knows he won't start all so he could get practice that might not actually be available to him if the season is canceled. I guess he could gray shirt, but I don't know if our administration would allow that and what kind of access he would have to the team if he were to do that.
