Also, while technically listed as a 3-4, we do a bunch of different things defensively. Last season, we had various packages for a number of situations. Sometimes we had defenders hovering around the line with no one really in any position.
Here's an example of that on a big play that snuffed out a late UTC drive.
I realize the differences between defenses can be slight, but this does not much resemble a "3-4" defense. I cannot read everyone's number, but I count what looks like 6 defensive backs. The only linebacker is Porter (37), who at that time was still a hybrid safety. Hope is on the line and appears to be shaded just outside the RT.
Up front, it looks like Seabrook, Stokes, Hodge, and Hope. We often used those guys in pass rush situations. That's technically 3-man front (by titles and positions), but the "NG" (Stokes, I guess) isn't lined up over the center. The pre-snap look appears to far more closely resemble a 4-man front than a 3-man front with two DEs and two DTs.
I wouldn't get too wrapped up in position titles and who plays where. The game situation dictates what we do defensively, and we are really creative on that side of the ball. We move in and out of defensive looks all game long.
