I think Lynn and Conn will likely hit the portal.
I can't remember, but thought when you have a coaching change you are allowed to offer basically a retirement package to any player. Essentially saying hey we need your scholarship, you aren't going to play, go away and have your education paid still.
The only two spots I feel semi comfortable with going into next year is Teddy LT and Nouili at OG (probably left). I think you have pieces, but you need to take probably +3 guys from the portal or juco.
I also think if you hire a good OL coach you can get more out of some of the guys on the line.
