I doubt any coach 'new' to Bill will instantaneously get as much leeway as it will take to influence him much. It takes time to build up the trust, as Payton did and Sparano has done. And I doubt Bill will just turn over, in what will likely be his last year coaching, his beloved D to a coordinator with a different defensive philosophy, or even one who favors considerably more blitzing.
"You live by the blitz, you die by the blitz". Another (in)famous Tunaism.
Nah, I don't see a Ryan type even getting hired, much less changing things much.
And for those who have mentioned Groh if he got canned at Virginia.... please, he was a savvy linebackers coach, but a dismal coordinator (in name only in NE under Tuna) and a worse HC. A total Parcells stooge. I'd like to see him coach the backers, for sure, but he Peter Principles out in the pros at that level - positions coach.
Best chance for us next year is some lightening bolt simultaneously striking Bill AND Zim.
Or canning 'em both.
