Top safety, slot CB, DE, an edge, DT gone. One area maybe improves - ILB. D line is thinner, safeties thinner with a big loss. May be able to replace him without a Major drop off but then we are three deep at safety without much depth. CB took a hit have depth but still 2 of back five gone. Between Fox, Brockers, Rivers, and Ebukam the DL/Edge rush lost a lot too. There may be some players stepping up BUT you also have to remember there is a new DC so may have to learn new schemes etc. It is not a let's run it back again scenario.
