Diaco was good at ND. Van Gorder was not. I was going to post the top defensive stats by team so here it go (without any adjustment for strength of schedule and only going down to the average level, relative to national averages in all regular season games played between FBS teams only):

Since I've been concerned about our Nebraska teams not forcing many fumbles, such that it's practically a statistical anomaly over the past several seasons, I thought it'd be interesting to look at the rankings for those also:

It's too bad Minnesota's recent HC made an a$$ of himself to some extent because we could do a lot worse...since he's tops if I just average these two numbers together, by program (not that I'm advocating a hire be made based on just numbers, even if you also considered the recruiting numbers for a particular candidate):
