Lauri or the other long term wing?
I mean are you asking too much from a single player? Solid defense + passing + shooting is fine for the PG prospect.. dont need to add self-creation there.
Shooting forces the coverage to be there on normal half-court offense, and late game clutch possessions the ball can be in the hands of someone else.
Look at who the top lead guards and playmakers are: Luka, Lebron, Steph, SGA, Ja, Donovan, Harden, Jrue, Trae, Haliburton, Fox, Lamelo, Cade, CP, Clarkson, etc. Right now, Anthony Black isn't advanced enough off the dribble and isn't a good enough shooter/scorer to create on their level. What the Jazz need is a really solid on-ball creator. He could be a guard or a wing. He'll effectively replace what Mike Conley does.
Lauri is becoming an elite play finisher, but he's not the guy who breaks people down off the dribble and creates an advantage. He's not a playmaker per se, but he'd be great playing next to a high-level playmaker.
