The Oklahoma City Thunder potentially have a major decision to make with Russell Westbrook after the departure of Kevin Durant. 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.

In the wake of Durant's departure, however, the Thunder were planning to take some time before making roster decisions. - See more at: http://espn.go.com/nba/story/_/id/16765088/oklahoma-city-thunder-mull-options-russell-westbrook
