No.
This team generally sucks at defense, but when Keyonte is on the court, it sucks a lot more. You cannot get around that. His individual defensive impact on the Jazz is overwhelmingly negative.
I have no idea why people are fighting the facts. This isn't some slight difference of opinion.
Find any type of analytics, any metric that measures defensive impact among current rotation players, and you will always find Keyonte at the bottom of the barrel. I wish I was joking.
On the whole, the entire Jazz backcourt is a disaster on D and cannot stop anyone. The fact that Hardy's schemes aren't exactly geared towards clamping down on perimeter shooters doesn't mean that the players are absolved of all defensive responsibility.
We can win when the opponent has a terrible shooting night, Lauri & Key get to their averages and someone else has a good scoring game. That's basically it.
