I think it might be time for us (and the Jazz) to come to grips with the fact that Jordan is not the player he was last year, and last year was a step down from previous years. He's currently shooting 29% from three, has as sub replacement level PER, is considered the fourth worst player in the NBA (!) according to BPM, His defensive rating is 511/543 and worse his offensive rating is 402/543. DPM says he's the worse top 7 rotation defender in the NBA. His true shooting percentage is 182 out of 196 players that qualify.
It's hard for me to say this but it might be time for him to move completely out of the rotation - maybe even take a few weeks off to rest. He's now functioning nearly entirely off of reputation and his +/- numbers for individual games tell the same story. The only time he's put together back to back positive plus minus numbers also happened to be when the Jazz went on a winning streak. Maybe the key to the Jazz wining is just replacing his minutes with well... anyone, as there's only 5 players that Vorp would say wouldn't lead to more wins if you replaced his minutes with theirs.
A few more things of note, he currently has 4 more games of positive +/- than Taylor Hendricks. His closest comparison statistically this year is Jordan Poole. According to cleaning the glass the Jazz are better off in every major statistically category expect for FT Rate when he plays. Clean the glass also projects he makes the team 11(!) games worse. He's got a single lineup he's played with more than 100 possessions that has a positive differential and that's only +7.
The argument for JC has long been: You just need someone who can put the ball in the bucket. Except the bucket getting is not happening this year. He's consuming more possesions than ever and doing it less efficiently than he's done his entire career. Currently he has the 38th highest usage rate in the NBA. But of the top 200 players in usage only Ausar Thompson, Josh Giddey, Russell Westbrook and Jordan Poole as shooting worse than he is according to true shooting percentage and only Jordan Poole (poor wizards fans) is shooting worse by effective fg%.
If the Jazz are looking to win (or even really be competitive) is it time to sit JC?
