Willie Cauley-Stein currently has a team option for the Mavericks this season. The Mavericks may decide to decline their option which would make him an unrestricted free agent. You may accept or decline this option, by default it will be accepted. You may also update his contract to perform actions such as a Sign & Trade.

Derrick Favors cannot be traded to a team aggregated with other players from his team because 2 months have not passed since he was traded for. He can only be traded away to a team by himself and other non-player assets from his team (draft picks, cash considerations, etc). This restriction expires after Sep 28, 2021.
