If there was a proven offensive mind out there I'd say maybe. Yet the truth is there isn't. Sure we can hope to catch lightning in the bottle like the OC in Houston but who is he bringing on as DC? There are so many variables and change for change sake isn't always a make for improvement. See Marrone for Rex Ryan as much as disliked Marrone I disliked Ryan more as he didn't play to his player strengths. Something I think McDermott has done but doesn't get enough credit for.
