I can't run the numbers right now, but I feel pretty sure that teams have at least 5 DBs on the feild more than 75% of the team... so we should be focusing on the actual main package (4-2 or 2-4) and not the false base packages (3-4 or 4-3).
Edge: Z Smith (Gary top backup)
DT: Clark (Lancaster top backup)
Edge: P Smith
ILB: No one (I believe Martinez and Goodson are both FAs)
Coverage ILB/SS: Greene/Campbell (no coverage ILB, have only SS for the role)
Nickel/Slot: Sullivan/Greene (Tramon a FA)
S: Amos (Greene top backup)
CB: Alexander (Sullivan top backup as Tramon is FA)
So major holes at ILB and CB/slot, with needed more elite play at DT.
