So I understand that this is probably more about what the Timberwolves received than what the Jazz lost, but it is worth noting that Kris Dunn in a similar sample size has been waaaaaaay better than NAW.
Granted, the Timberwolves have a lot of head room for a guy that is positive, energetic, and a professional, but it sounds like that is most of what he's bringing. They "fleeced" us for a guy totally 'balling out' with a 14.2 PER, 7.7 points per game, 1.7 assists per game, and 0.4 steals per game.
What I'm getting at is this: the Timberwolves are desperate for anything good and he's playing the best he ever has which is technically on the lower-end of mediocre (a 15 PER is calculated by the average level of production by that metric for an NBA player). So, sure, would've been nice to keep him (away from them), but he wasn't an important part of the franchise's long-term plan and he's likely going to come back to earth since it is A SEVEN GAME SAMPLE SIZE. In return, the Jazz look like they'll improve their own pick this year (A LOT?) and they got a pick that on even-odds has an 87% chance of conveying as a 1st and a ~11% chance of conveying as a high-end 2nd in case the Lakers are just abysmal and lucky.
Did I mention Dunn has a 21.2 PER and a box +/- that is FIVE TIMES HIGHER? Small sample sizes for lottery talent playing for their lives can produce wild results.
