High Plains Drifter
As is the overall philospohy. Marinelli and guys of his ilk are the "bend but don't break" types, not fully committed to an attack posture, preferring to kind of ride along between the 20s and hope we don't give up any big plays, but then get aggressive in either red zone. You can't turn it off and on. You're either an attacking D or you're not. He wants to pick and choose and pretend OCs can't predict it. They can and do. They know he's gonna get aggressive inside his own 20 and they know he's gonna be blitzing when you're inside yours.While there might be some similarities, Quinn's defensive style/sets are a little different than Marinelli's were.
Quinn is from the attack at all times school. He will use the single-high safety look and he will disguise his coverages. But his front seven are attacking no matter where the ball is on the field. His DL is attacking upfield at the snap, disrupting the offense and his LBs are playing downhill and will be lined up closer to the LoS. His D will give up a big play here and there though. But once the unit gets tight and he has the personnel he wants, that will be fewer and further between. Quinn is much closer to the Jimmy Johnson philosophy.
