An awful lot on Haskins shoulders, but him just being adequate in his Freshman season would be a big upgrade on it's own.
If you get McLean back, and Ngakoue doesn't jump.. the d-line looks better. Excited about Keihn.
The O-line starts to actually look good next Summer. That's huge.
The Secondary is a complete mess if Likely leaves, and Diggs (if he becomes official) doesn't move to CB.
I think the new coaches would have to be thinking about moving a WR like Etta-Tawo to DB... his hands are suspect at best, but has good size/athleticism. So maybe it could work.
Also have to look for JUCO's, and grad transfers... position needs work.
