The way I see it, no real talent comes out, but maybe you can get enough bodies out there to at least be able to teach what you need to teach this spring. None of them will make it to the summer anyway, so why not get a few warm bodies that can at least line up and run routes so the QBs, RBs, OL, and 3-4 legit WRs can learn something this spring as opposed to wasting 15 days of practice.
On a side note, I hope the "freshmens" are ready, bc/ they're going to play, even if they aren't.
