It's true that it is hard to build a contender with highly paid, non top 30 players, but when your star level players are on rookie level contracts then it works just fine.
Usually/Always (I can't think of any exceptions) teams wait until they know they have a rookie who is going to be a star level player before they start acquiring they guys that fit around them. So it's really hard for me to imagine the Jazz drafting Flagg, for example, and not at least wanting to see him play a little before adding guys like Turner around him. On the other hand, if Lauri takes a step forward and/or one of our young guys look amazing, then we might already have the pieces that make the FO feel like they can start adding guys like Turner.
We also might just be the exception to the rule where because we have Lauri we get impatient and decide to just hope our 2025 draft pick is a stud and skip some steps to a degree.
