It's easy for you to say these things now after the fact but like i said, hindsight is 50/50 and judging a player's talent level during a nba draft is completely subjective. How do you define a player being the most talented and the best available?
Some would say the player who was the most nba ready(Jahlil Okafor, Derrick Williams, Jabari Parker, Trey Burke, etc) and some would say the player who has the best measurement and raw athleticism(Frank Ntilikina, DedEx, MKG, Thon Maker, etc).
See? you can find busts in both of these categories. Some would still argue that we really should've drafted Giannis in 2013 but the reality is that none of us has a time machine to know that what we were looking at was the future MVP of this league.
But what we really don't need a time machine for is the basic needs of this team. i mean it doesn't take rocket science to know that this Jazz team needs some size, athleticism and defense across 1-4, which makes Herb Jones the most fitting candidate.
Had we selected Herb Jones, at least we would've gotten a chance to see what we truly have because he would've gotten ample opportunities to play. We don't know what we have with Butler. And unless we go into a full teardown next season, Butler may be gone before we could ever find out
