The Oklahoma City Thunder are finally back together as a stable unit, and have a strong scorer off the bench. Durant and Westbrook finished the season virtually injury-free, and Enes Kanter emerged as one of the league's best sixth men.

The Golden State Warriors finished the season with the best record in NBA history, and won the championship last year. The San Antonio Spurs have added two of the league's top tier power forwards, and are stocked with championship-winning veterans.
