OKC and their young forward couldn’t reach a deal on an extension, so they’ll allow him to test free agency next summer. The Oklahoman reports: “Jeff Green will become a restricted free agent next summer. Oklahoma City Thunder general manager Sam Presti confirmed to The Oklahoman that contract negotiations between the team and representatives for the 2007 fifth overall pick have ended. The two sides had until Monday to reach a deal on an extension for the fourth-year forward. But barring an unexpected last-minute concession of some kind, Green will be allowed to test the free-agent market in July. ‘Signing a player to an extension is certainly a positive but has become more unique,’ Presti said. ‘We explored the concept and had positive dialogue, but we will have to revisit the discussions in the future.’”
