I mean, consider this for a moment: Dennis Lindsey has repeatedly stated he and the Jazz org view Rudy as a top ten player in the NBA. That means that they view maybe --MAYBE-- 9 players as being better, in terms of overall impact. None of those nine possible players are going to have the same unique kind of impact that Rudy does. If we assume this to be true, then there is literally no player on the planet who can replace Rudy Gobert. Dennis Lindsey has also repeatedly emphasized the importance of defense as the team's primary philosophy, and it's clear that they have designed their defensive structure entirely around Rudy Gobert.
So, no - saying the Jazz have no interest in trading Gobert, in any reasonable scenario, is not the result of a poor understanding of business, or an over-investment in sentimental nonsense; it's an obvious deduction made from ample evidence about what the team has built, and how they intend to move forward with it.
PS - KAT is not one of the nine players who are arguably better than Rudy Gobert.
