Before the NBA season was suspended due to the COVID-19 outbreak, the Utah Jazz were sitting pretty in the Western Conference standings, occupying the 4th seed while being only a few games behind the number two team in the conference. Things were going smoothly for the Jazz: their stars, Donovan Mitchell and Rudy Gobert, were having terrific seasons, and they had a solid supporting cast around their cornerstones. However, following Gobert's reckless behavior around the team in the midst of the Coronavirus pandemic (a virus that he coincidentally ended up having), trust has been lost of him for some Jazz players, namely Mitchell.
And while that beef supposedly has been worked out, we can't truly know how each party feels behind closed doors. If the relationship between the two stars is dire, common logic would dictate that one would get traded, likely Gobert since he is the one who is the cause of the issues.
That being said, Utah would be better off trading their Mitchell instead of their 2-time Defensive Player of the Year.
