It is just being realistic. SLC even in the best years was routinely mentioned as the worst destination for the NBA players. Two most recent centerpieces the Jazz had, Hayward and Mitchell, clearly wanted out. Heck, even Conley did not want to come to the Jazz but was forced to.
But more specifically, you are looking at the things from the GM perspective and not as an 18-year old star. Playing with quality role players like Markkanen and Kessler will get you nothing when you are 19. While playing with LaMelo immediately makes you the center of attention for media and social media. And, btw how many endorsements Kessler and Lauri have compared to LaMelo? Like, both of them combined?
I think that the most realistic way for the Jazz to build the team is to lean heavily on foreign players like Memo, AK and Lauri. Even if the Jazz somehow get Flagg there is a high chance that he will try to find his way out by the time the Jazz are competitive. And, anyway, personally as an NBA fan I would not want Flagg wasting his entertainment and competitive potential in the wasteland that the Jazz is likely destined to be for the next several years: no other star prospects, second-rate veterans, young and inexperienced coach, the lack of team culture. The Jazz are in the total disarray and all they have is praying that somehow a future superstar falls into their lap, sticks with the team and fixes everything. It rarely works.
Oh, and also, you should try to remember that you are on the discussion board where different people WILL have different opinions and that is by design. If it annoys you you may want to explore something called Mirror Work. "Mirror work is a
self-help practice that involves talking to yourself in the mirror, often using
positive affirmations. This technique aims to improve self-esteem and foster a deeper connection with yourself. "
