Both worlds I commish have instituted 4 year win minimums. 55/125/195/280. In any consecutive season, you have to achieve those minimums. Not sure if it will stop tanking but no one will be able to run 3 consecutive 60 win teams out there. And, if you play for the minimums, it's 55, 70, 70, 85, so you can get caught with an major injury. And, with 70 wins, you probably won't get a top 5 pick.
