One option the team is considering is attempting to renegotiate and extend the contract of Westbrook before he can become a free agent after next season, sources told ESPN.
If Westbrook chooses not to extend his contract this summer, multiple league executives told ESPN they believe the Thunder will consider fielding trade offers for Westbrook.
In the wake of Durant's departure, however, the Thunder were planning to take some time before making roster decisions.
With Durant going to the Golden State Warriors, the Thunder can make some moves to free cap space to keep Westbrook long term. The All-Star guard is slated to earn $17.8 million this season, is eligible to add up to $8 million to his contract and can add years to the deal and take himself off the free agent market in 2017.
With the salary cap expected to leap again next summer, however, Westbrook would stand to earn more money by waiting and signing a new contract with the Thunder or another team then.
Because of the type of contract Durant has decided to take with Golden State -- one year with a player option -- the Thunder cannot sign-and-trade him, meaning they will receive nothing in return for losing their franchise player.
