Russell Westbrook and the Oklahoma City Thunder have made serious progress on a three-year, $85 million contract extension.

No deal has been finalized but there's momentum.

Westbrook would have a player option for the 18-19 season.

The Thunder have been pursuing an extension with Westbrook since Kevin Durant left the franchise to sign with the Warriors.

In the structure of a proposed deal, the renegotiation would move Westbrook’s salary in 16-17 from $17.8 million to a $26.5 million max salary.
