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.
