At a real high level, I think if the DL does not get adequate pressure and if the ILB and S positions (I am not referring to this year's S position) is poor, I just don't see it. The personnel is woefully inadequate. The middle of the field is a sieve and any QB can toss a pass in the short to mid distance middle of the field, can't he?
I would guess Caper's schemes are especially vulnerable to the above lack of personnel.
