Der Jaeger
Generational EBUG
There'd be some weaknesses, but that's what I'd do as well. Put Johnson at safety, add in a LB, and run a somewhat tradiational 4-3. It'd be a combination of 3 CBs and a safety, which "could" hinder zone coverage scheme disguises.The is the shift that a lot of offenses are making in reaction to defenses playing a lot of base nickel defense and 2 high shells.
It is the cat and mouse, back and forth as offenses and defenses shift and change.
Joe Marino has talked about how they could play Williams as SAM in 3 LB sets and shift TJ to more of a box safety type role and taking the SS off the field in those spots. It will be interesting to see if the change at DC leads to more ideas like that or if they continue to play base nickel most of the time regardless of whether there is heavy personnel out there or not.
McDermott would need to add some wrinkles to that to make sure QBs and OCs didn't figure it out right away.
A player like Cooper DeJean at the other safety would essentially turn it into 4 CBs and no safeties, which could also be interesting in terms of options.
James Williams from Miami is a LB sized safety who would also bring some serious scheme flexibility.
