Defensive Metrics Don’t Ever Agree … Except On Rudy Gobert’s Great Season

It’s not flashy of course (14ppg, 13.5rpg, 2.7bpg, 67%fg), so he only gets brought up for the lowlights or when pocket watchers pocket watch... but he’s having a GOAT-tier defensive year.
More so, he has the Jazz still winning (7 of their last 10) even without Conley and Mitchell.

Defensive Metrics Don’t Ever Agree … Except On Rudy Gobert’s Great Season
While his competitors may disagree, the data suggest that not only is Utah Jazz center Rudy Gobert running away with this year’s award, he’s having one of the best defensive seasons in modern NBA history.
The broad indicators bear this out. Gobert’s play is the primary driver behind Utah’s top-ranked per-possession defense outside garbage time. This season, the Jazz are 11.9 points per 100 possessions better defensively when the Frenchman plays compared with when he sits, per Cleaning the Glass. That’s the largest such gap in the NBA among players with at least 1,000 minutes. In fact, Gobert’s defensive on-off split is one of the largest of any high-volume player over the past 15 years:
Fellow Jazzman Mike Conley, for instance, holds the NBA’s second-highest defensive on/off differential this year among those high-volume players — but that’s partially because Conley has played over 90 percent of his minutes alongside Gobert.
Gobert’s consistency across metrics stands out. Each of them is calculated with different variables and weights; a quirk in one could, theoretically, inflate a given player’s value somehow. Gobert’s current campaign rating at or near the top of every single one is hard to ignore, especially with so many of the game’s defensive greats sitting alongside him.
The picture is the same when looking at situational data. The pick and roll is much of the league’s bread and butter, easily its most common offensive play type, and no one shuts it down like the Stifle Tower. Per Second Spectrum tracking data, when Gobert defends a pick-and-roll screener, the offensive team scores just 0.851 points per chance — the lowest number among the 65 centers who have defended at least 300 such plays this season. Gobert has the length and mobility to effectively guard two players at once:
For the 2020-21 season, opponent possessions featuring an isolation with Gobert as the primary defender have yielded 0.779 points per chance. That’s fourth-lowest in the NBA among 66 players who have defended at least 125 isolations, per Second Spectrum data, trailing only Draymond Green, Richaun Holmes and Julius Randle — and a big improvement from earlier in Gobert’s career.
A half-decade-old viral clip of Steph Curry turning a younger Gobert around off the dribble has shown remarkable staying power; once or twice a game, some unsuspecting young guard gets Gobert on a switch and assumes it’s easy pickings, only to be rudely awakened to the reality:
