Manny reverted back to a 4-3 when we played BC in 2018 iirc.
We have the personnel to throw multiple fronts/looks but it might be worth thinking about moving Carter/Frierson/Smith to LB full-time. Or we could keep throwing Ragone out there and hope for the best.
Even if you moved all three to LB there's a bit of a logjam at DB with Hall, Blades, Ivey, Bolden, Avantae, Harrell, Washington, Couch, C. Williams, Balom, Clarke, Dunson
McCloud, Joyner and Huff are our only healthy LBs at the moment:
Jennings -hip
Steed - knee
Brooks - shoulder
Cave - shoulder
Flagg - knee
