2017–18 Oklahoma City Thunder season
The 2017–18 Oklahoma City Thunder season was the 10th season of the franchise in Oklahoma City and the 52nd in the National Basketball Association. This season was headlined by the acquisitions of All-Star players Paul George and Carmelo Anthony in trades with the Indiana Pacers and New York Knicks respectively, in addition to the reigning MVP Russell Westbrook signing a five-year extension worth $205 million. The trio was dubbed the "Big Three" as well as "OK3". The Thunder clinched their playoff berth for the eight time in the last nine seasons with a win over the Miami Heat in a rematch of the 2012 Finals on April 9, 2018.
They finished the regular season with 48–34, which clinched the 4th seed. In the playoffs, the Thunder faced the 5th seeded Utah Jazz in the First Round, a team led by rookie Donovan Mitchell, and lost in six games.
After averaging a then-career low 16.2 points per game during the season, Anthony was traded to the Atlanta Hawks in the offseason, ending the Thunder's Big Three experiment. The season also marked the end of long-time veteran Nick Collison's career, after 14 years. Sometimes referred to as "Mr. Thunder", Collison appeared once in the finals, and following his retirement, left Jeff Green of the Houston Rockets and Kevin Durant of the Brooklyn Nets as the last remaining active players who played for the then-Seattle SuperSonics.| Round | Pick | Player | Position | Nationality | College/Club team |
