Tanking will never be the same again. Or, at least, that was the idea when the NBA Board of Governors voted to enact Draft Lottery Reform starting in the 2019 offseason.
This is how the new system will work. The teams with the three worst records in the League will have a 14 percent chance at the number 1 pick, instead of the current system which awards a 25 percent, 19.9 percent and 15.6 percent chance to the 28th, 29th, and 30th worst clubs respectively. This will also have a trickle down affect to the other Lottery Teams.
