1. The Jazz have too many young prospects
The primary reason why the Jazz were so exciting coming in was because they have quite a few prospects to look at. Walker Kessler, Keyonte George, Taylor Hendricks, Brice Sensabaugh, Colin Williams, Isaiah Collier, and Kyle Filipowski are all exciting in their own way. The problem is some of these prospects got in the way of each other.
Observers justifiably complained when there were long stretches where Hendricks and Williams seemed invisible. That was because other Jazz prospects like George and Collier had the ball in their hands for most of the time. That wasn't anyone's fault in particular. The problem was that, at times, there were too many mouths to feed.
Maybe the Jazz will get a better look at some of their young players when they head to Vegas. Hopefully by then, they'll be able to feel out what exactly they have in all their young players.
