It seemed a bit of a stretch to say that his run defense woes were only because he lined up at NT, but I wanted to check his snaps to see how many times he lined up over as a nose. For a baseline of the player/position he's going to play I pulled up Jalen Carter.
Carter played NT 18 times last year
Bresee 66, down from the 84 his rookie year.
50 fewer snaps at NT probably helps him not be in bad position, but I can't say adding those 50 snaps to 3Tech suddenly makes him a better run defender either.
