It's a little bit offtopic, but the plus-minus does funny things for the solid defensive starters on very bad or very good teams. Usually what makes the team very bad or very good is their starters: the difference between benches is usually much smaller. And the solid defensive players do not make the starting five either very good or very bad - that's the production of stars. But as a result the plus-minus of those solid starters is unfairly elevated or dragged down.
For example, the best plus-minus on the last season's Celtics belongs to Derrick White, the second best plus-minus on the 23-24 Nuggets (just a hair below Jokic!) - to KCP, and the second highest on the 23-24 Cavs - to Max Strus. And on the teams struggling this year Agbaji and Kessler are unfairly bad on the struggling Raptors and Jazz and Ingram is the worst for the Pelicans.
The best plus-minus players on the Jazz are all off the bench, led by mighty Patty Mills and Eubanks, and they are likely to remain among the leaders going forward because the Jazz' bench is not nearly as horrible as their starters.
