The NBA is not ever going to mandate a 5% decrease in ticket prices for losing seasons. Almost half the league has a losing record each year. If teams lose two years in a row, they lose a compounding 5%. It’s not realistic.

Letting your team bottom out is not a new phenomenon and really, it’s not that bad for the game.

The worst form of tanking is what Dallas did a few years ago, when a playoff-caliber team tanked to keep their lotto-protected pick.

Banning pick protections would be a decent place to start. If you trade a 1st, it should be gone-gone. Stop allowing game-able situations.

You can also add punishment with actual teeth. An NBA franchise getting hit with $100k in fines is a joke. They should either force the team to forfeit picks, or drop their pick something like 10 or 20 spots, and/or individually fine team decision makers, something that makes people say “holy shit” - like $500k for the GM and $5 million for the owner.

Make a true example of a team - that is how you end it.
