I feel pretty good about the defense actually. Sark & Co addressed the needs well enough in the portal that a good rotation of bodies should yield steady, if not stellar performance. I expect great play from Alfred Collins and probably good performance from Norton, Lole, and Savea along with the rest of the interior DL roster. They will rotate interior bodies. They don't have to collapse the pocket really, if they can plug their gaps and hold, our stellar stable (emphasis added) of Edges and LB's can take care of the rest. And there is also Nance's effect to consider. He should add some disruptive wrinkles to the defense. Reports from practice were that some of his alignments caused issues for the OL at times. Pressure is more likely to come from the Edges this season and I'd expect AC to also add to that occasionally up the middle. He's so fast and athletic off the ball, he will be disruptive in his contract year.
The secondary has been talked up a good bit too, and while I'm hopeful, it's also kool-aid season. Hope they really take a step forward this season with their technique and playing the ball. Improved pressure off the Edges should help them.
