First thing is that so far offensive efficiency across D1 is at its highest level in at least the last 30 years. Prior to the pandemic, the average efficiency ranged from 1.00 PPP in 1998-99 to 1.05 PPP in 2013-14. Starting from the 2021-22 season, it has gone 1.03, 1.05, 1.06, 1.07, and now this season it is at 1.10. It will likely drop as the season progresses, but will still probably be the highest ever. Lots of reasons for the increase, but that's all to say that yes, we are giving up way more points than any other Collins team, but it's still not his worst defensive team.Fair points, though Torvik stats indicate our D is much worse than our O. Is there data on how much faster we play? I think it explains a bit but our D is still the problem. Makes sense to me we struggle late in games with a young team and without an alpha.
By pure adjusted PPP, at 1.06 PPP this is the 2nd-worst NU defense in the last 30 years, just behind the 2007-08 season that probably should've gotten Carmody fired, but he signed the recruiting class headlined by Nick Freundt and some afterthought named John Shurna.
But by rank across D1, this isn't even Collins' worst D. The 2014-15 team was ranked 151st, and the 2019-20 team was ranked 150th. What do those teams have in common with this one? Playing freshmen lots of minutes. Interestingly, our issue on defense is not letting the other team shoot too well, it's that this is the worst defensive rebounding team since Carmody's last season. Our opponent's eFG% is the 5th-best of any Collins team, behind the 2016-17, 2018-19, 2015-16 and 2013-14 teams, and just ahead of the 2022-23 team.
As far as tempo, we're still well in the lower half of D1. While we are playing decently faster on offense - about 1-2 seconds faster on offense than the past few years - it's counterbalanced by having the longest defensive possession length in the country, which is about 1 second slower than the past few years.
