Thinking back over the last 10 years, the Jazz pinned their hope on the youth of their time back then and we ended up seeing the the following guys pass through,.
Donovan Mitchell
Rudy Gobert
Royce O Neale
Gordon Hayward
Alec Burks
Trey Lyles
Enes Kanter
Rodney Hood
Derrick Favors
Trey Burke
Dante Exum
Seems to me that overall, apart from Donovan, most of the others peaked during their time with the Jazz (albeit sone only due to injury striking unfortunately after leaving the Jazz). I'm by no means religious in any way, shape or form, but beyond Don and Royce (and putting aside Rudy for the time being), it's interesting to note that most when on a downhill trajectory not long after moving on.
