Two-way contracts
Per recent NBA rules implemented as of the 2017–18 season, teams are permitted to have two two-way players on their roster at any given time, in addition to their 15-man regular season roster. A two-way player will provide services primarily to the team's G League affiliate, but can spend up to 45 days with the parent NBA team. Only players with four or fewer years of NBA experience are able to sign two-way contracts, which can be for either one season or two. Players entering training camp for a team have a chance to convert their training camp deal into a two-way contract if they prove themselves worthy enough for it. Teams also have the option to convert a two-way contract into a regular, minimum-salary NBA contract, at which point the player becomes a regular member of the parent NBA team. Two-way players are not eligible for NBA playoff rosters, so a team must convert any two-way players it wants to use in the playoffs, waiving another player in the process.

During the 2021–22 season, two-way deals will work a little differently than usual. Rather than being limited to spending 45 days with their NBA teams, two-way players would be eligible to be active for up to 50 of their team's 82 NBA games. And instead of having their salaries by how many days they spend in the NBA, they'll be paid a flat salary equal to 50% of the minimum player salary applicable to a player with zero years of service.

Going to other American and Canadian leagues
The new league of all players is NBA G League, although some players have returned to their former team, as shown below. The NBA contract status of nearly all players is unrestricted free agent, and the rest is stated otherwise.

Going overseas

The following players were on NBA rosters during the previous season, but chose to sign with overseas teams after their contract expired and they became free agents. The players became free agents at the end of the season unless noted otherwise. The list also includes unsigned 2021 draft picks who signed with overseas teams, but excludes unsigned 2021 draft picks who were already playing overseas before the draft.
