One problem is this is hard to see happen on tv. In person at the stadium you see the swaps as the offense takes the field play to play. So, for many it’s hard to follow what you mean here. The nfl coverage seems to do a better job catching this with more sideline angles that show the personnel swapping/matching on the defense. In the super bowl it showed up A LOT.
A 3-4 is, at its simplest, a 5-2 with what used to be called "ends" standing up as OLBs.
Very true (for those watching i the eighties think Carl Banks and LT on opposite sides of the line both as standup LB’s with LT almost always rushing and Banks more of the true LB role from a 4-3). as is the 4-3 under for that mattter that M Manuel seems to run. Each look a bit like a 5-2 with a fair amount of versatility and, I think, try to match up the best d lineman on the best matchups. What is odd, is the 4-3 under seems to use more 1 gap speed rushing inside, ala the Seahawks and, at time Rams with a Donald. With the size we are using under Grantham Gators.0, you’d think he’d play that style intentionally (not just matching). And, We aren’t playing our 3-4 big double gap bodies yet claim to be base 3-4. I know
@ltraz identified above matching the offense due to heavy outside man coverage, but it still seems odd how little we play a “big” 3-4 or even 4-2 (with two gap assignment) nickel. That could have helped a bunch versus Missouri.
