Hard to know completely but in my opinion, the players we have at the DL can make the switch. Big A, Broughton, Ojomo, and Goram Welch seem versatile enough to play either the 5 tech of the 4 man front or the 4 tech of the 3 man front. Coburn and Sweat have prototypical size for a 3 man front NG or a 4 man front 1 tech. Overshown can be an OLB or walk up end but is a little lite. Mitchell is the rangy MLB in a 3-3-5 but no idea who plays the other LB. Maybe Prince can be the stand up monster type position where he drops occasionally into coverage and offers some exotic blitzes across the front. Either way, the DBs must play better for any scheme to work.jmho.
