Con?: LaVine might not be too keen on joining the Jazz
Believe it or not, this it not based on Utah's reputation for failing to lure star players. It's based on speculation on LaVine's previous actions. Back around the trade deadline, the Bulls discussed trading LaVine to the Pistons, per The Athletic's James Edwards III.
Coincidentally, LaVine opted for season-ending surgery, ending any chances of him going to the Pistons. While nothing has been confirmed, it's possible that LaVine did not want to play for one of the worst teams in the league. The Bulls don't have too much to brag about, but at least they've done well enough to reach the play-in.
The Jazz are not one of the worst teams in the league as currently constructed, but despite what they have and knowing the Western Conference is a bloodbath, it might not be too appealing no matter where they're located.
It may not be his choice in the end, but the Jazz ended a turbulent era with Donovan Mitchell and Rudy Gobert. Among their options, they definitely want to avoid that coming back. If the Jazz want LaVine, it would be in their best interest to have something else up their sleeve to appeal more to him.
