Great job with the lists compiled. For sake of discussion I'll remove my orange colored glasses for a different perspective.
Quarterbacks
Rating: 4 / 10. Dobbs was pedestrian at best as a freshman but is smart and appears to be working hard to improve. Peterman was a dumpster fire in his only playing time. Neither of the freshmen were ranked 5* can't miss QB's out of HS. I'm hoping someone steps up and shines but until then we're only hoping for the best.
Running Backs
Rating: 7.5/10. Like you said, this group has a ton of potential! Hopefully they will stay healthy and the cream of a very talented group will emerge as a force. Right now unproven.
Wide Receivers
Rating: 10/10. Great group of talent. Just need someone to get them the ball.
Offensive Line
Rating: 4/10. A real shame past recruiting has left us with wholesale replacement of the OL. Again, no 5* can't miss types stepping in so my fingers are crossed hoping these guys have developed.
Tight End
Rating: 8/10. We have a solid group with good potential, but still unproven. AGREED
Special Teams
We have a solid group with good potential, but still unproven.
Rating: 7/10. .
Defensive Line
Rating: 6/10. We're putting together a solid group on the DL. Again, unproven and no can't miss 5*'s (unless KM commits). Lot's of potential to battle for PT so hopefully the cream again will rise.
Linebackers
Rating: 8/10. I think I like this group even a bit more than yourself.
Secondary
Rating: 8.5/10. I really like this group. Sutton is proven and TKjr, Gaulden, and double Berry are some elite talent IMO. Just need to prove it.
