I would trade Lauri if we can get good return. For a simple reason, we won't be good before years at best and it does not match with Lauri timeline. At that stage we better trade all ''old'' players that have values and make a full rebuild through picks and salary space.
Regarding Giannis, zero chance he play at the Jazz. He already set up a list of teams he is open to play for and Jazz are not on the list. He will go to a flashy destination, LA, Miami, NY or near his current place, Bulls.
For me the question will be if DA finally admit he was wrong for 2 years and make the right turn. We can't attract star players ( small market, SLC...) unless we overpaid and overpaying a star right now with average players to put around him is not a recipe for success. Finds young guys, develop them and when they are at a decent level, try to get a star.
And who know we may finally pick a good player so having 3 and 5 could be interesting.
Anyway, i think we need a 3-5 years clear strategy from now on.
