Sources: NBA presents 3 comprehensive anti-tanking proposals - ESPN

The NBA presented three comprehensive anti-tanking concepts to its board of governors Wednesday as part of this week's meetings in New York, with modifications expected to each before a formal vote in May, sources told ESPN's Shams Charania.

Each of the three proposals would be radical departures from the current setup. They have one thing in common: bringing teams that make the playoffs into the lottery process. From there, they change dramatically.

In the first proposal, sources told Charania, 18 teams — the bottom 10 that miss the play-in tournament, and the eight that qualify for it — all will be part of the draft lottery.

The bottom 10 teams will all have an equal 8% chance of moving up in the lottery, with the remaining 20% of the odds being split among the eight play-in teams in descending order from 11th through 18th.

All 18 spots would be drawn as part of the lottery in that format.

In the second proposal, sources told Charania, 22 teams — the bottom 10 teams that miss the play-in tournament, the eight that qualify for it and the four playoff teams that lose in the first round — will all be included in the lottery, and will be ranked according to their record across two seasons. The last part, weighting teams by their record across the prior two seasons, is how the WNBA weights its lottery system.

Under that system, each team would need to reach a minimum win total floor in each season, to mitigate the need to lose every game possible. For example, if the minimum floor for an individual season was 20 wins, a team that went 14-68 would be 20-62 for lottery purposes. And if a team wins 40 games one season and 20 games the next season, it would go in as 30 wins for the lottery.

In this system, the top four spots
