Certainly sounds like McDermott's defensive philosophy, even though you'd take a very different route with respect to personnel and alignment.
Reads right to me. Thanks for taking the time.
Might not be relevant, but (in keeping it Bills related) I'm oddly reminded of Jauron's defenses here, and how--while mostly mediocre--they actually gave vintage Manning and the Colts trouble on the road, playing that measured, conservative coverage-based scheme. The vaunted Cover-2/Tampa-2: keep everything in front of you. Rangy middle linebacker and dynamic safeties, zone-heavy CBs with eyes in the backfield, four down-linemen...I mean, not when the Bills ran it. But ideally.
