That shouldn't really matter. The advanced metrics adjust for the quality of the opponent. That's what the "Adj" part of AdjD means.
This, and also most P5 teams non-conf schedules are going to have a lot of those types of teams. I can just watch the games and tell you that our defense has absolutely tanked from where it was prior to Jan 1 (or thereabouts).
Quincy looks a lot less aggressive. Coleman brings it on D one game and then is okay-to-terrible the next. Harmon looks serviceable one game and then the next looks completely helpless and clueless. Luke is being hunted by opponents. Domask had to take on a much bigger role on offense - first with TJ being out, second with taking on more ballhandling responsibility - which I think has hurt his defensive play. TSJ doesn't look as aggressive defensively as he did.
We are 3rd to last in the country in forcing turnovers. How the hell do we have the best collection of length & athleticism in the conference and be this bad at forcing turnovers? If not for Coleman's 5 steal games, we'd assuredly be dead last in that statistic.
The defense is something that should've been figured out a month ago.
Anyway, to get back to the point-- yeah, I think our defense actually was extremely good earlier in the season. If you want to throw out all of the cupcake games, that's fine. Marquette beat us, but scored only 71 points and there wasn't a parade of layups and dunks. FAU scored 89 but are an elite offense (we shut them down at the end of the game when it mattered). Tennessee scored 86 but only shot 44% and I don't recall a layup line in that game either and they're ranked #5 in the nation. Even looking at Oakland who we held to 53 points, they're 112 in AdjO so higher than Maryland (160) who just put up 80 against us and not much worse than Penn St (91) who dropped 90 on us. Colgate's offense is also comparable to Maryland and we held them to 57.
I think its pretty clear that there was some big regression at some point. I am starting to side with those who want us to scrap all of the switching. We have the personnel to pull it off, but its not working. So let's stop doing it, please.
