The Oklahoma City Thunder are awaiting an answer from Russell Westbrook on their offer of a supermax extension at 35 percent of the salary cap.

Westbrook can become a free agent in 2018 if he doesn't sign the supermax.

"I wouldn't really say that one's a negotiation," said Sam Presti.

The Thunder are essentially waiting for an answer from Westbrook on the offer.

James Harden agreed to a similar supermax on Saturday.
