I think at least two QBs and two RBs are basically a given. Thompson is a question mark at best. I'd be surprised if Smothers, Purdy and Haarberg all stay. And Watson might decommit. But we'll probably add a transfer, especially if Thompson leaves.
Yant sounds like he's basically gone. Which doesn't hurt my feelings. Grant could very well leave.
Probably 2-3 of WRs as well. Palmer is one. I guess IGC is already gone but I wasn't counting him. Hardy and Grimes seem unlikely to see the field here. Tommi Hill might look to start over (again).
I don't see a bunch of OL defections though I continue to be surprised Lynn adn Conn are still here. Likely getting at least a couple of transfers so that might push a couple to look elsewhere.
The to-be-sophomores on the DL - Weaver (now OL?), Black and Buckley - seem questionable at best.
We should return a solid group of LBs but Snodgrass seems to have been passed by and not much has been heard from Kpai, Malcom or Gbayor. Likely 1-2 out of that group.
Nelson and Mathis might have put in their time in college.
Tyreke Johnson seems to be a non-factor. Omar Brown made some noise but barely saw the field. NPG doesn't seem to be figuring it out. Probably a couple other defections if Fisher doesn't come back.
That's 22 or so without any real big surprises, of which there are always a couple.
