DL would go big SDE (could Jackson play this?), 1-Tech in Poe, 3-Tech in Dorsey and then WDE in Hali. Houston would be the SLB and line up right beside the SDE similar to a 3-4 look. DJ would likely be the WLB if I were to guess and we would bring in a MLB (draft Arthur Brown? or a FA pick-up?).
Another article talking 4-3 under scheme.
Basically this defense still asks a lot from Hali (WDE) and Houston (SLB)!
