WNBA free agency is upon us, with teams extending qualifying offers to 2022 reserved free agents as of Jan. 1. As the activity heats up, we made a cheat sheet to get you ready for what should be an eventful free agency period.

A reserved free agent is any player who is out of a contract and has been in the WNBA for three years or fewer. These players can negotiate only with their previous team. Teams have until Jan. 14 to extend qualifying offers to reserved players.

Any player with four years of service in the WNBA is considered a restricted free agent. These players can negotiate and sign with any team in the league, but their previous team has the “right of first refusal” to match any offer and try to retain the player.

Unrestricted free agents have completed a contract and played at least five years in the WNBA. A player can also become a UFA if they are cut by a team and passed through waivers without being claimed. Unless designated a core player, a UFA is free to negotiate and sign with any team.

A core player, as mentioned above, is unable to negotiate with other teams, but the team that has cored them must offer a one-year supermax contract. The team and player are able to negotiate a longer contract, but the tag will stick to that player for the length of the contract unless the player is traded, waived or retires. Each team has one core player designation, such as Phoenix with Brittney Griner and Los Angeles with Nneka Ogwumike. A player can be cored for only two seasons.

Teams may begin contract negotiations with free agents on Jan. 15, and players may officially sign contracts starting Feb. 1.
