UFA Unrestricted free agent

RFA Restricted free agent

Unrestricted free agent

An unrestricted free agent (UFA) is free to sign with any team, though some unrestricted free agents have options on their existing contracts that, if exercised, may impact their choices.

Team Option

A team option grants the original team the right to keep a player for another year.

Player Option

A player option grants the player the power to decide whether to stay for another year or become a completely unrestricted free agent.

(In either case, if the option is refused, the player is completely unrestricted, free to sign with any team.)

Early Termination Option

An early termination option gives the player the right to end a signed contract. The option cannot be exercised before the end of the fourth year of an existing contract. If the player declines to exercise the option, he remains with the original team. If the option is exercised, he is free to sign with any team.

Restricted free agent

A restricted free agent can sign an offer sheet with any team, but the player's original team can retain him by matching the terms of that offer. The original team is said to have the "right of first refusal."

Who's Gotten Qualifying Offers?

John Schuhmann, NBA.com

When the season ended, there were 46 free agents set to be restricted free agents, where their teams could match any offer they received.

But in order for a player to be a restricted free agent on Wednesday, his team needed to extend him a qualifying offer by Tuesday. If signed by the player, that qualifying offer is a binding, one-year contract (like with Greg Monroe last year).

If the player signs an offer sheet from another team, his current team has three days to match it. If he doesn't, he can also sign a new contract with his current team.

26 of the 46 potential restricted free agents received qualifying offers. The other 20 did not. Here's a rundown…
