To be fair, the Jazz are planning on trading two prime all-stars plus a bunch of other assets before their tank. They aren't starting at bone dry zero. They look to have at least 2 and sometimes 3 first round picks every year for the next 7 or 8 years. It is going to be really hard to suck on purpose if two or three of our first and second year picks hit, especially if you get a head start with some of the Knick players (which I am still not sold on BTW.) Philly took a while, but they made some really bad picks along the way and didn't really start where we are.
Additionally, I feel like if the Jazz suck for 4 or 5 years, there will be a tremendous cost in fan support. Jazz fans are rabid because the Jazz win. Imagine what Ute football crowds would look like after 4 consecutive 3 win seasons. There has to be hope. This board, who are probably the most resilient of fans, barely survived the Corbin era. Jazz aren't pulling a 5 year tank.
Dallas screwed up because they wasted assets on Porzingis and now they let Brunson go for nothing. Their result wasn't inevitable.
