B-Ref and NBA.com apparently have very different methodologies for calculating O-Rating, D-Rating and Net. B-Ref uses a formula developed by Dean Oliver that is supposed to focus on the obvious miscues made by the player in question. I believe NBA.com is more about the actual points scored/allowed per 100 possession while said player is in the game.
In 10 games as a starter, NBA.com has Wood as 118.4/118.7 for a net of -0.2 (bench 25 games was 114.9/109.6 for a net of 5.3)
In 10 games as a starter B-Reference has Wood as 122/112 for a net of +8 (bench 25 games was 111/113 for a net of -2)
It makes sense that NBA.com would show a different story. Wood is +4 in total +/- in the 10 games as a starter the way NBA.com calculates +/-. The team has a winning margin of 5 points in those games. What I don't know is what to think about Dean Oliver's methodology and why it is so different than the actual game results.
To be fair, Wood's numbers as a starter and the team's numbers during those starts are really skewed by the Chicago blowout that Luka missed. The more recent 9 starts in a row paint a more positive picture, but nowhere near as positive as the B-Reference numbers paint.
My numbers are straight from NBA.com. Where did you see those numbers on NBA.com? Can you link to the specific page?
