I think it's a joke too, as I've said in other posts.
No player is going to want to play through April and maybe into May and then be prepping for the next season 2-3 months later. Wear and tear will be extreme. In fact, it could have significant injury impacts the following fall season as bodies were not able to get the necessary time to rest and recover. As I said in another thread, if it were me, I'd ask to redshirt in the spring if I had one available.
And as I've also said -- no player with any professional football aspirations and eligibility to declare for the draft will play college football in the spring. Not a single one.
Spring football would be a shell of what it should be. And would likely be a detriment to the following fall season. It seems likely to overlap with college basketball -- and good luck with that. The NCAA tournament is from mid-March to the Final Four during the first week of April -- and somehow we'll have college football on top of that? C'mon now. Seems like a sports fantasy -- I'll give it that.
