The first part is simply not true, at least in the way that I think we normally use "random" (certainly in the way I'm trying to use it). Randomness is a feature of probability. You can't predict the next outcome or any single outcome after that, so it is random in that sense. But it's also mathematical in the sense that over many outcomes (a long period of time in terms of the NBA lottery) patterns can be predicted with a fairly high likelihood.
Of course the probability is higher to get a "good" outcome with a lower finish. (But the top (by far, I'd argue) outcomes in the example I gave went to teams that finished in positions 7 & 8 (Ja and Zion)). So in the limited history we have so far with the current lottery odds, it hasn't helped all that much to finish as first or second worst. If you want to take a 100-year sample (maybe even a 50-year sample), then yeah, it will probably be better for the teams that finish 1st and 2nd worst. But I don't think it's worth the wait of keeping our team bad that long to find out. The likelihood of this higher probability being helpful in any singular draft is not very high.
The whole point I'm trying to make is that the odds are simply not so good even for the best-odds result to reliably use that strategy as the central strategy for team-building.
You’re right on all of this.The unfortunate reality is that there is no benefit to not tanking in the NBA. So however marginal the gains are for a single year, there are no gains for winning 20 games versus 30 games. In theory you should have more to begin with at 30 games. But it really depends on what’s delivering you those 30 games in terms of what that means for the future.
Generally, tanking is an often overrated strategy in my opinion. But the obsession of tanking is just a symptom of how fans have started to view the NBA. The NBA is not a league that lives on day to day competition. People don’t care about day to day competition, the only thing that matters is the future and the larger context. Winning games does not matter unless it means something for tomorrow.
I do feel like people buy into tanking because there is feeling that the team is working towards a title…even if they are disregarding the extremely low probability and unreliability of that strategy.
OTOH, I don’t really buy into the negative effects of tanking. I don’t think a culture is created when you win 30 games versus 20. If you win 30 games on the backs of vets who won’t be here in a couple years, you are worse off than the team that wins 20 on the backs of young players who are talented but simply not experienced enough and/or not ever going to be good enough. This is true independent of the draft incentive.
Also….More wins =\= better culture. You can win the maximum amount of games, have everyone happy, and it still be a negative basketball culture IMO. The most recent version of the Jazz was a perfect example. Trust team had its ups and downs, and there was constant talk about whether or not the players were best buds. Truth is, I don’t think the buddy buddy stuff mattered. I think the reason they failed is because they built bad habits during the regular season that set them up to fail in the preseason. This was true when they were best buds and had the best record and also when they were passive aggressively throwing jabs at each other in the media. The noise didn’t matter….what mattered is that they built a rigid brand of basketball that could not compete in the playoffs and did not have the ability to divert from their habits. You can obviously build bad habits from being in a situation where wins don’t matter, but that can also happen when trying to maximize wins.
