For what its worth, over the past five games our offensive rating has been 101.4, good for 20th in the NBA, but our defensive rating has been 87.4... good for 1st in the NBA. By a lot. The gap between 87.4 and the current #1 defensive team is larger than the gap between the #1 defensive team and the #29 defensive team.
When you compare our ratings per game to our opponents average ratings for the year, it paints an even rosier picture. The Jazz, on average, are scoring 0.94 less points per 100 possessions than their opponents typically allow... and holding their opponents to an insane 14.8 less points per 100 possessions than their opponents typically score.
So very small sample size, but since we're all trying to speculate on the Jazz w/o Kanter, so far, the offense has fallen off a bit - not much, but a bit. The improvement on defense is offsetting it several times over.
EDIT:
I decided to also include the 4 other games Gobert started this season. Over those 9 games, the Jazz offensive rating is 104.7 (good for 11th in the NBA) and the defensive rating is 93.2 (1st in the NBA by a wide margin).
Taking into consideration the offensive and defensive ratings of their opponents during those 9 games, the Jazz, on average, are scoring 2.1 more points per 100 possessions than their opponents typically allow, and they are holding their opponents to 8.8 less points per 100 possessions than their opponents typically score.
Honestly the most bizarre thing about this data is that the Jazz allowed 3 of their 9 opponents to post a better offensive rating than their average, and all 3 of those teams are lottery teams. Might indicate an issue with getting up for weaker opponents.
