Answer is definitely shaded by the "post-trades" roster and current injuries, but Tillman, DJ Williams, Ratliff, Paea, Houston, Peppers, Wootton, probably bostic and Allen are all better than their respective counterparts on the current team - and most of those play positions that have a bigger impact than the '22 roster's advantage which is mostly just Safeties. This is effectively comparing a 30th ranked defense with the 32nd (since Roquan trade) one though, if you want to argue that the difference is negligible i wouldnt disagree.
Edit: For objective measurement of how bad current D is - since Roquan trade the D has given up 34.6 ppg - this is 2 points higher than the worst defense of the last 2 decades, worse than the 0-16 Lions team, and is happening in a year where scoring in the NFL is DOWN by about 10% across the entire league. We'll see if they continue this pace but I mean the Mike White dismantling kind of points to this not just being a streak of bad luck.
