The problems with our D last game (and honestly in Alcorn who didn't have the horses to burn us) were not with the secondary scheme. You may not like a heavy reliance on zone and playing off the ball at the snap, but in terms of design fundamentals Woody knew where the sticks were and had guys in position to clean up screen passes, etc. That much is different from Roof, and Roof did a lot of quarters coverages. In any scheme, there's going to be openings for receivers. I would like to be more versatile, but overall I like what Woody is doing because it complements what the front 7 are supposed to be doing, and it gives us the opportunity to roll into different coverages to confuse the QB (cause of the INT we snagged), and a QB who is being taken out of rhythm is going to miss guys in front of their receivers in the zone to make picks or struggle to make accurate and on-time throws allowing the secondary to close and make a play on the ball or wrap-up.
Execution on the other hand...that was problematic. Mostly it was problematic in a few screens where people lost their leverage or took the wrong pursuit angles in clean-up. That part was much better in the Alcorn game, and this probably reflects heavily on the ejections and injury problems.
But the bigger problem was the front 7. The leverage problem (or wrong assignment) was amplified, leaving wide open lanes for QB to pick up yards on the ground, some big runs, and otherwise space to maneuver away from pressure. That part was a significant issue against Alcorn, and we were simply fortunate to athletically make up for it, and really they also did a poor job executing on their opportunities.
That problem of containment and pursuit angles is precisely why we got burned for 2 consecutive kickoffs (and really the first 1 was 1 missed tackle away from a TD too). Thankfully, it's not a talent problem, and having it exposed so egregiously may provide energy to fix it. But god help us if we don't. Knowing your assignment and sticking with it is the one requirement for Woody's defensive scheme to be decent. Adding athleticism to that makes it great. I know we've been hearing about aggression and I'm talking about control, but really the assignments themselves are aggressive, and the reads are minimal.
