Very true. Signing a superstar and/or trading for a superstar is also not just an unsure thing, but it's not even on the table. Or at the buffet.
What is at the buffet though is a lottery pick. 1st, 2nd, 3rd....I'm not really too worried about which one. It's out of our hands anyway. We can't control how many games other teams lose, and we can't control the ping pong balls. Even with the worst record in the league, our chances of landing a top pick are 25%. Hell, only one team(Orlando) in the past 15 years finished with the worst record in the league and won the lottery.
To put it shortly, I think people are overstating the odds of landing the number one pick, as well as what that will bring. There are so many variables.
The quality of players - not every draft has multiple franchise players in it...some have none
The quality of scouting - never in my memory has there been a draft where the 5 players who eventually turned out to be best from that class were drafted 1-5...even the 2003 draft had Darko at 2
Intangibles - sometimes, you pick a can't-miss, NBA-ready, going-to-be-at-least-as-good-as-Clyde-Drexler guy, and he ODs on coke later that night...you can't control that
Injuries - whether it's eventually like Yao or right away like Jay Williams or Oden
LeBron factor - ok, so you avoid all this stuff, draft a Hall-of-Famer and he then leaves in free agency because you're a small market team...like the Jazz are
When you start with only 25% of getting that first pick, and add all these other factors, what are the odds of actually getting a player in this draft who will lead the Jazz to the championship. High enough for me to have no issue with us playing badly right now, but certainly low enough to not want to put all our eggs in one basket. There are people in this very thread proposing getting rid of just about anyone needed to finish last. Burks, for goodness' sakes! Just for the odd chance that we land the next Dirk or LeBron or Pierce. And for the much higher chance that we don't and end up with Anthony Bennett but without Burks. And possibly others, because you have no idea how blatant tanking will affect players. Yeah, let's sit Hayward because playing him might win us an extra 2 games, and then he leaves for Phoenix next summer.
People are acting like tanking would 100% ensure we get the second coming of Michael Jordan. And when they're asked, like you were, to back that up with statistics, then you beat a hasty retreat. All you can say is that according to your logic, picking first is better than picking second or third because it is. Why can't you then come up with numbers that show that? Or any numbers that would show significant benefit to drafting first as opposed to second. Oh, right. It's unrelated events.
