It means Adams' second season in the NBA is over and he will now have plenty of time to reflect and look ahead to next season.
It has been a big year for the 21-year-old centre who has taken on more responsibility at the Oklahoma City franchise and improved his statistics across the board.
A tough injury toll was a major factor behind the Thunder missing the playoffs this year for the first time since the 2008-2009 season, with injured star Kevin Durante missing most of the season.
His partner in crime, Russell Westbrook, also missed a good chunk of the season, as did forward Serge Ibaka. Westbrook ended the season with the best NBA game average, 28.1 points, but ESPN.com reported he would much rather have had a spot in the playoffs.
"I never really thought I'd be winning anything close to a scoring title," Westbrook said. "But I'd rather be in the playoffs than win the scoring title, to tell you the truth."
