Whatever feeling you have about Trae, there is no nearly available super-star out there who makes sense for Utah currently. You should look to capitalize on the negative PR he has taken as a gettable super-star who isnt going to cost you an inflated price.
Trae has had the same level of playoff success that the Jazz have produced for the last 26 years. One conference finals appearance. He's a perfect fit next to Lauri/Walker.
You give up Keyonte/Hendricks and 3 first and you still have a huge cache of picks to go out and get another borderline all-star type of player to put next to Lauri/Trae.
You keep Simone, sign him to a nice long-term deal. You get Grimes. You trade for DFS. You sign Dunn long-term. You have a really good foundation to build upon and a lot of room to make changes as the years go on.
