I don't see what changed (or what will change) from last year as far as the defensive scheme goes.
Gap integrity is not our strong suit. If you want to have a disruptive defensive line, then you are going to sacrifice gap integrity, and that is going to lead to chunk yardage plays - both run and pass, but I am referring more so to run. That's one of the reasons JJ led the team in tackles. When a big OL comes unblocked at our MLB, most times our guy isn't going to be able to make that tackle and its gonna fall to the safetys to clean it up.
If anything, I think it can be fixed on the back end. More pre-snap confusion, better personnel groupings on 3rd down, picking our spots to be aggressive and not 100% relying on it, maybe covering the slot receiver once in a while lol.. all these things are fixable. However, I think we will remain susceptible to accurate QBs, especially those that can throw on the run and those that can make the proper pre-snap read and get the ball out quickly.
I think Manny is who Manny is. Many of us have been in agreement that we would rather err on the side of aggression. I know I would.
