Braxton Jones needs to be relegated to backup tackle, so there's a premium weakness.
I rank our weaknesses in how bad the player is and the premium of the position. I would say C, LT, edge 2 and OG respectively. Envisioning the off season, free agency should get us a starting OG, with the draft netting the LT, EDGE and center. I only did it that way because you can't get the premium positions as cheaply as a guard.
