Alot at once. I think a base defense with Hoecht, Benard, Thompson, Johnson, Bishop helps the run defense on early downs. Overall, Johnsons strengths and at times alignments are that of a box safety. Imo Mcdemott’s strength at defense was with two high safeties. My biggest question would be Johnson deep Third. Playing quarters and 2 safety mitigates those concerns. Also offer the flexibility to play single high with Johnson on the slot. Secondary needs juice. Sitting Rapp and keeping Poyer out of rotation is only avoided imo by moving Johnson. Johnson is the OG of the room make him the table setter at safety.
