NBA 2023 Offensive and Defensive Ratings (Nov 7) - eviltoast

Plot explanation

  • ORtg & DRtg: Offensive ratings (ORtg) are estimates of how many points teams score per 100 possessions, and higher is better. Defensive ratings (DRtg) are estimates of how many points teams’ opponents score on them per 100 possessions, and lower is better.

  • Four quadrants: Teams in the top-left quadrant have the best net rating (estimated point differential per 100 possessions), and teams in the bottom-right quadrant have the worst. The bottom-left quadrant represents teams who are better defensively than offensively, and the top-right quadrant are those who are better offensively than defensively.

    good work plotting the ratings, it is a very welcome addition to this community :)

    some suggestions for the next version of the chart: (- inverting Drtg axis was already suggested before)

    • same scaling of axes, so that 5 points of rating is visually the same length for Ortg and Drtg
    • adding some diagonal lines to mark levels of the same net rating
    • equalizing logo size, right now some are huge and some are tiny
    • in some cases logo background could be transparent

      Great suggestions, thank you!! I’d written this code during the summer for an MLB plot (EPA+ and OPS+, which are standardized), had some downtime today, and decided to give this a quick shot

        Their frontcourt is huge: KAT at PF and Gobert at Center. Gobert is known as a defensive center, and he contributes 14 points a game for a 38 mil salary. I think that’s a good chunk of it, but I don’t know the Wolves well

        They’ve been aggressive. They’ve got above average or elite personnel at every position defensively, with the possible exception of Towns, but he’s been much improved defensively as well this year. They been running good schemes, covering each other’s backs, rotating on the perimeter, getting in passing lanes and playing phenomenal on ball defense. Jaden McDaniels is criminally underrated. I don’t understand how he wasn’t in the dpoy conversation last year. He guards the best player on the opposing team almost every night and really throws them off their game.

      They’re hidden under the Kings - they have basically the same ratings (below). Thanks for catching this!
      Sacramento Kings (ORtg, DRtg): 109.8, 115.0
      New Orleans Pelicans (ORtg, DRtg): 109.9, 114.9

    Oohh i like this. keep them coming! Though it is unusual to have the best net raying on a top level quadrant.

    Have you explored inverting the defensive rating values?

        Barring major injuries to your team, your Celtics will be in the top right corner next time (I’ll make top-right the good quadrant next time :)

      Thanks, I’ve already thought of some improvements for the next one!

      I think if defensive rating values are inverted, the best net rating would be top-right and the worst would be bottom-left. That’s probably a more familiar quadrant orientation (it reminds me of math). I might explore some green-red-orange/yellow colour shading. All suggestions are welcome :)

    It’s early. Most teams have only played 7 games. I’m not surprised to see the Celtics, Nuggets, and 76ers (Maxey is looking like a super star) leading the pack. I’m curious to see how the Bucks do this year: Picking up Dame and parting with Jrue Holiday looks like it’s affecting their defence. The Pacers and the Timberwolves look like opposite teams (all offence or all defence, respectively). I’m not surprised to see my Raptors with a woeful offensive rating - that half-court offence is painful to watch

    Damn. If the Lakers could have somehow ended up with CP3 to orchestrate the non-Bron minutes I feel like they and GSW would be swapped rn.

    Dude is averaging nearly 8 assists off their bench

      You may very well be right. But Lamelo would have twice the number of assists he has if he weren’t on the Hornets
