Unless VJ has an amazing pre-draft process, I don't think teams will take him in the top 3. They'll take Coop, Dylan and Ace ahead of him. I think VJ will primarily be seen as an off-ball 2-guard. He's not advanced enough yet to play on the ball full time. If you watch Baylor games, they're initiating through Robert Wright and letting him create off the dribble, play after play. If VJ had a more advanced handle, burst and change of direction, he could beat defenders consistently. But until that happens, he still mostly relies on other guys to set him up.
I also do think he's going to measure out on the smaller side. I'd be very curious to know where the Jazz have VJ vis a vis Kasparas.
