I agree 100% about tackling. Definitely an issue this year that seemingly was not last year. And that is in part coaching. And certainly part of the 3rd downs issue is directly tied to tackling.
I was mainly trying to just refute an overreach that Morris somehow ruined a great defense. In many areas they are still top 5. In a few they are actually better than last year. And in some, yes, they're regressed too much. Some of the comments on the board act like this defense went from #1 to 25th. It hasn't.
