Gobert had started in all 65 of his team's games before Saturday's matinee, but the 7-footer was a late scratch against the Thunder because of a leg injury. In his place, backup Jeff Withey made his first start of the season.
As it turns out, Gobert is pretty darn important to the Jazz's success.
Utah's offense suffered greatly without Gobert setting screens and rolling to the basket for buckets at the rim. The Jazz's defense, meanwhile, was almost unrecognizable.
The Jazz entered the afternoon with the NBA's third-ranked defense, allowing 101.8 points per 100 possessions. With Gobert sidelined, Utah's defense against OKC was about 14 points worse than usual over the course of 100 possessions, according to NBA.com.
It is, admittedly, the smallest of sample sizes. And the Jazz were also without starting power forward Derrick Favors, himself a solid defender, against a bruising Thunder frontline of Steven Adams and Enes Kanter.
"This was probably the worst game to miss both of them," Jazzman Joe Ingles said. "We needed one of them."
And Gobert, whom the Jazz signed to a $100-million extension earlier this season, is the anchor on defense.
Few squads cause opponents more trouble in the paint than Utah. Teams shoot 57 percent in the restricted area against the Jazz, according to the NBA's stats. And Gobert's impact in the paint is unmatched. No player in the league defends more shots at the rim (10.5 per game) than Gobert, according to SportVU, and opponents are converting there 43.2 percent of the time against him.
With Gobert sidelined, OKC looked at times like it was simply running a layup drill, en route to outscoring the Jazz 58-44 in the paint.
"I'm not surprised that they dominated the paint," Jazz coach Quin Snyder said when asked about Gobert's absence Saturday.
That absence caused problems for Utah, but it might actually help highlight Gobert's case for Defensive Player of the Year, as voters pick from among a field of candidates headlined by Golden State's Draymond Green, San Antonio's Kawhi Leonard and the Jazz's own French Rejection.
In the short term, things are looking up for Utah. Gobert was hurt Wednesday in Houston, when James Harden's knee collided with his right leg and the injury started to bother the Jazzman at the start of his warmup routine on Saturday.
Gobert was expected to undergo an MRI, though he was expected to be ready Monday against the Clippers.
"We want to be smart about everything," Snyder said, calling the decision to hold Gobert out "precautionary." "Hopefully it's nothing more than that."
