A detailed look at what Grantham’s 3-4 scheme entails, along with some strategies to attack it, is posted over at Rocky Top Talk.
There’s some good stuff in there, although I’d quibble with his “natural response” solutions towards the article’s end, simply because Grantham hasn’t stayed in a 3-4 when faced with three and four-receiver sets this season. As he said to Fletcher Page,
… I would say it’s probably been about 60-40 in favor of 3-4. Some of that’s based upon situation of the game, personnel, types of plays they’re running, things like that. So we’re always going to be multiple in what we do. We’ll work to put the players in the position to be successful.
I’m not sure how much of Georgia’s problems on defense are purely scheme-related right now, anyway. I’d put a lot more of it on this:
… Georgia has some mitigating factors here. The first is simply personnel turnover (which we ought to understand better than most right now), but it’s likely equally to do with a shift from the 4 lineman-base Martinez used to the 3-4 Grantham prefers. However, even as a 3-4 it does some things differently. This is a new defense that we’re seeing, but fortunately this is still a new defense for Georgia, too.
