Russell Westbrook has never complained about players on the Oklahoma City Thunder, either this season or in the past, a source tells ESPN.

Westbrook prefers to stay out of most front office affairs.

Westbrook is believed to be "very happy with the players on the team and the outlook of the roster."

Westbrook can sign an extension worth approximately $220 million over five years this summer. Westbrook can become a free agent in 2018.
