these concepts have been discussed to curb tanking:

First-round draft picks can be protected only for top-four or top-14-plus selections

Lottery odds freeze at the trade deadline or a later date

No longer allowing a team to pick in the top four in consecutive years and/or after consecutive bottom-three finishes

Teams can’t pick in the top four the year after making the conference finals

Lottery odds allocated based on two-year records

Lottery extended to include all play-in teams

Flatten odds for all lottery teams
