The Thunder has exercised the third-year options on the contracts of Kevin Durant and Jeff Green, keeping them with the franchise through the 2009-10 season. The team had until Oct. 31 to exercise its options on last year’s No. 2 and No. 5 overall picks or both players would have entered next summer as unrestricted free agents. The Thunder holds fourth-year team options on both players, which must be extended by Oct. 31, 2009 to keep Durant and Green through the 2010-11 season. If the Thunder exercises the fourth-year options on Durant and Green for 2010-11, both players could become restricted free agents in the summer of 2011. The Thunder, however, can begin negotiations for contract extensions in July 2010. The team will have until Oct. 31, 2010 to reach an agreement with both players on extensions to prevent them from becoming restricted free agents. Durant, last year’s Rookie of the Year, averaged 20.3 points, 4.3 rebounds and 2.4 assists in 80 games. Green, who joined Durant as an All-Rookie First Team selection, averaged 10.5 points, 4.7 rebounds and 1.5 assists.
