I'm certainly looking forward to hearing more.
My thought process is along the lines of: doesn't this mask deficiencies in the secondary and help the front-7?
Playing more zone should allow the safeties to be in a better position to bail out a beat corner, which in turn should allow the guys up front (especially the line) to take more chances going after the quarterback, right?
In theory, playing off more should create more turnovers. Our DL is going to get after it no matter what coverage Ryan calls. From what I've seen, man-to-man creates more coverage sacks than zone. If the QB doesn't find that whole in the zone by his second read, he'll either have to check down, throw it away, or tuck it.
With quality pressure from the DL and the occasional LB blitz, most QBs are prone to throw the ball too soon in a disguised coverage. Ryan can really mess with QBs, especially young ones, with this stuff. They can rock coverage to the strong side and walk up to press pre-snap.
Antonio Cromartie seemed to play loose man on almost every snap. A lot of people complained about it, but it made perfect sense. He has long arms, he's fast as hell, and he
had the ability to recover if he got beat. It wasn't his job to jam wideouts. He was either supposed to force them inside or just not get beat over the top - he did a really good job with it for a while.
