That's a really weird alignment. Dane's definitely where an OLB might be, but there's really only 1 DL out there to go with 5 LBs. Cunningham and Tully have a hand on the ground on either side of Big Vince. Then Guyton, Mayo and Fletcher who are all ILBs out there, and all front-6 guys rushed the passer.
McCourty and Arrington are at corner, with Chung coming into the picture and I assume Meriweather deep. So I'd have to guess there's a third safety somewhere deep like Meriweather while Chung is playing that safety/LB hybrid. In that case, then both Guyton and Dane are OLBs.
Which is all a really long way of saying it's not really a normal set-up. Then again, who knows what BB will devise now without Cunningham?
