Worth is what each player's projected DRBL wins would cost on the open market over the rest of his contract, and salary is what he is owed. Surplus is worth minus salary, except that a team can decline a team option or cut a non-guaranteed year, and a player can turn down his option. These are the same estimates shown on player pages.
The team total of +$126.6M adds up each player's middle estimate and ranks 2nd of 30 teams. Every player's own range is wide, so read the total as a rough guide.
Left out of the total, not counted as zero: Kentavious Caldwell-Pope, Jordan Hawkins, D'Angelo Russell, Cole Anthony and Mamadi Diakite (waived) and Cameron Boozer and Karim López (no recent DRBL seasons).
