Tanking is ruining NBA basketball. Can math save it?

"At the end of the regular season, the 14 teams that fail to make the playoffs enter a lottery to determine the first four slots in the draft order. The odds are assigned based on the teams' performances during the seasonthe worst teams get the best odds. This method is meant to promote a healthy, competitive league over time. But in a way, its' had the opposite effect: a number of teams spent the latter half of this season in a race to the bottom, intentionally losing games to secure the best possible odds."

"Tanking is against league rules, but very difficult to prove. The NBA has floated a number of fixes. On May 28, the association will vote on a proposed 3-2-1 system. The name refers to the number of lottery entries, in the form of Ping-Pong balls, that different teams would receive, according to the plan. It would flatten the odds overall, but also penalize the three teams with the very worst records, making it optimal to perform badly but not too badly."

"Some have already pointed out the system's pitfalls, however. Ironically, this type of format will ensure that the bottom three teams are truly the weakest ones, says Justin Olmanson, a professor at the University of Nebraska-Lincoln. Under thi"

The plan would flatten odds overall while penalizing the three worst teams, aiming to reduce incentives to lose too much. Critics argue it could still entrench the weakest teams at the bottom.
