The Jazz wouldn't send anyone to the Timberwolves, but participating in a trade like this is still a favor nonetheless.
The Utah Jazz have already done the Minnesota Timberwolves quite a few favors since 2022. Most recently, they cut quality wing Johnny Juzang just for him to get a perfect flyer with the Timberwolves. A four-way trade idea involving the Jazz and Timberwolves would basically have them do it again, even if they wouldn't be sending any of their players to the Timberwolves.
