This is an interesting point. You can filter by date on Torvik, and if you go through the Penn St. game on 1/8 (next game was USC where things kinda started to go downhill) Torvik has us as the 5th best defense in the country. That would paint the view that the defense is actually good when we are healthy. But then you filter from the Iowa game onwards, when we supposedly got healthy again, and in that stretch where we went 5-1 our defense is #107 in the country! Yikes.
So was it injuries? Was it initially injuries initially, and then other teams figuring out what we were doing and us failing to adjust? It's really hard to say. But last year our defense was #25 on Torvik through December 31, 2023, and then from January 1st on was #109!! It's starting to feel like not-a-coincidence that our defense starts out strong and then ends up extremely weak.
