I do make up my mind early on prospects. It honestly only takes watching a few games and checking some high school tape. As I've said before, I look at their physical profile, their physical talent and their competitiveness. I do that with every prospect, and I've found that, based on past experience, it's more accurate to do this than to be swayed and talked into changing my mind over time. So from my perspective, I'm not allowing my judgement to be clouded. GG is going to be a very, very different player by the time he turns 21.
Jazz are completely rebuilding their team. They're redesigning their entire roster. It isn't clear what types of players or play style they want to put together. However, to raise their ceiling, they're going to need one or more star players with more on-ball creation than Lauri. The players in this draft with that potential, imo, are Wemby, Scoot, Amen, GG and Sensabaugh. Jarace, Keyonte, Ausar and Jett have some star potential, but they're more likely to be high-level starters. Miller, Whitmore, Black and maybe Dick are likely to be high-level complementary players. When it comes to drafting, I only care about star upside, especially if the Jazz are going to be drafting in the lottery.
At the end of the day, it doesn't matter. The Jazz never seem to pick my favorite players. Strangely though, Sam Presti often does.
