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. Two-way contracts must be signed prior to January 15, with their salaries being fully guaranteed on January 20.
