The other thing to be aware of is that teams whiff on their picks. If the Jazz had 3 or 4 picks in this draft, followed by 3 or 4 picks in the next draft, then they could feel confident that they'll come away with two or three real stars they can build with. A few of those other guys will get pushed out the rotation and ask to be moved. And a few others will bust.
In other words, the Jazz may need 6 high first-round picks in order to really hit on 2 or 3 of them. Then that gives the Jazz a foundation of young talent to develop and build on within the same time window. It really makes sense to acquire and use a glut of picks all at once, or plan the rebuild through the draft all to take place in two back-to-back drafts.
The Process shouldn't be to tank for 5 years. The Process should be to sell your assets and acquire a ton of picks all within 2 - 3 years tops.
Get Jaden Ivey, Jalen Duren and Tari Eason in this draft. Next year, get three more studs. Then move forward with the ones that really pan out.
