The DRtg for that pair was 115.0, a hair below league average (114.8).
That league average is the highest in league history by a pretty good margin (2020-2021, 112.3). The no-defense all-pace 1980s had league average ORtg around 108, but in the last few seasons it has gone over 110 and is trending higher.
I remember a lot of comments about the Spurs' DRtg last year (120.0) being the worst in league history. As an absolute number it's a true statement, but relative to league average it isn't.
For example, the 2014-2015 Wolves had the worst DRtg in the league at 112.2, while the league average was 105.6. That Wolves team had a worse defense relative to league average by both absolute difference (-6.6) and percentage difference (+6.25%) than the 2022-2023 Spurs (-5.2, +4.53%).
All defenses suck now when compared to the past. The best DRtg in the league in 2022-2023 was the Cavs at 110.6, but just 3 seasons ago that would have been league average and in 2017-2018 it would have ranked 21st in the league.
