This has been discussed some and we've had some interesting proposals and I may have missed if someone already suggested something like this.... but I think the way to solve tanking is to simply make "build through the middle" option better. So being a feisty play-in loser or a bubble team would be incentivized. Here is one example of how it could be achieved:
Teams are grouped in 3 groups for draft lottery:
Group 1: Bottom 8 teams based on regular season record
Group 2: Teams outside bottom 8 but also outside playoffs (so 9-14)
Group 3: Playoff teams
Top 3 picks are drawn with even odds between 8 Group 1 teams
Picks 4-6 are drawn with even odds between 6 Group 2 teams
Pick 7 onwards are awarded based on reverse standings for the remaining 22 teams who didnt win in either one of the two draws
The catch here is, that group 2 has a higher chance to win even though the prize is smaller. Top tier talent (e.g. all the "generational" prospects) still go to the worst teams helping them out of the cellar, but being in the middle group actually gives you a better chance to top 6 than being in the bottom 8 does. The downside of this is that would someone actually fold their play-in game for the higher odds? That is bad revenue-wise in the short term, so I'd imagine not many owners would be in favor of that.. but still its arguably worse PR-wise than what currently transpires annually.
