Sure, the odds may be low, but that doesn't change the fact that a team needs to try and draft those player. You simply need to have a transcendent player if you want to win. Maybe the Jazz have decided that they're going to acquire a disgruntled superstar via trade whether that player wants to come here or not. That's another approach. That has its risks as well.
But put another way, let's say the Jazz take Taylor Hendricks in this draft. He works out fine and becomes something like Jerami Grant, Robert Covington, or in a better-case scenario, he's like Trey Murphy.
In the grand scheme of things, so what? He's like your third or fourth guy. The Jazz give those types of guys away all the time now.
