Your averages average to 3.4. (To be exact it's 3.40 followed by 6 90s, so you're obviously rooting for LVN, lol)

Safety and special teams sounds about right. A little generous on the other positions.

Wow Andy, you must have woken up on the wrong side of the bed!
I found your ratings REMARKABLY pessimistic.

First of all, I don't understand why you'd consider injuries part of the equation. Not because they don't impact play, but because they are "outside of anyone's control." I think the only fair way to grade would be to assume the injured players will return at their former level, anything less is "Nervous Nelly" country. (Now, I think it's fair to include Lloyd's injury, because he has literally never shown us anything for two years)

Secondly, somehow you "don't trust the special teams," but that should not be part of a ROSTER analysis. Additionally, look at what we DO have: An All-Pro level punter, a coverage player who was playing at an All-Pro level before his injury (Neimann).
A former Pro-Bowl punt returner (Skyy Moore). A former All-Pro kick returner (Nixon)
And although it is not roster-related, if you "don't trust the special teams" because of their history, it would only be fair to add some optimism with a new ST coaching staff (and what appears to be a new emphasis on rostering players who have been good college special teams players).

I don't know how you could rate the edges as anything less than a 4; Parsons is a 5, and VanNess looked like a 3.5/4 when healthy (That's your two starters which averages 4+) and Sorrel and DDS and Cox as a backup group are EASILY a 3 at worst, and I suspect there are a lot of teams who would HAPPILY trade their backup edges for ours, which means "as a backup group" they are a 3.5+

And maybe the biggest WTF of all, your rating of the WR group. How many starting three WR groups in the NFL would you trade for our Watson/Golden/Reed trio? How many teams have better than a Williams/Moore/Melton backup group? (and that's not even considering the high ceiling of Sturtivant and Neyor)

Yes, I'm an optimist, but I'm not wearing Green-and-Gold glasses; I just feel you were REALLY harsh in your grading of the above. It really sounded like someone operating from a place of apprehension, rather than a neutral place.
