Daniel Orton has refuted a report that the Oklahoma City Thunder has promised him it would select him in the 2010 NBA Draft if he is still available when the team selects in first round. According to a reporter for the web site DraftExpress.com, Orton has canceled his six remaining workouts and “speculation is that he may have a promise from OKC.” Orton attempted to silence that speculation Thursday morning. “There are rumors that the Thunder have promised me something, and they haven’t,” Orton wrote in an e-mailed statement to The Oklahoman. “I discontinued my workouts for other reasons.” Orton, the former Bishop McGuinness High standout, entered the draft after one season at Kentucky. The Oklahoma City native has been mentioned as a possibility for the Thunder since early in his freshman season with the Wildcats. Per team policy, Thunder general manager Sam Presti does not comment on conjecture and made no exception about Thursday’s report. The Thunder this year also decided to not announce who it is bringing in for pre-draft workouts, though it is believed that Orton was in town earlier this week to showcase his skills to Oklahoma City’s coaches and front office brass. But the 6-foot-10, 260-pound Orton is projected to be a good fit for an up-and-coming Thunder team in dire need of talented post players. Orton projects as a defensive-oriented center in the NBA, someone in the mold of Boston’s Kendrick Perkins. And at just 19, Orton has ample time to blossom into a long-term threat anchoring the middle behind Russell Westbrook, James Harden, Kevin Durant and Jeff Green. Some NBA observers, however, have questions about Orton’s potential, ranging from his productivity in college to his health. Orton averaged 3.4 points, 3.3 rebounds and 1.4 blocks during his freshman season. But he averaged only 13.2 minutes for the Wildcats while playing behind DeMarcus Cousins, a projected top 10 pick. At McGuinness, Orton tore the anterior cruciate ligament in his left knee and missed the majority of his senior season. There is concern in some circles that Orton’s knee could become a chronic problem in his career. It’s a red flag that has caused his draft stock to fluctuate between the lottery and the end of the first round. The Thunder currently owns two selections in the first round, the 21st and 26th overall picks. Oklahoma City also is slated to select 32nd, the second pick in the second round, as well as 51st overall. The 2010 NBA Draft will air Thursday, June 24 at 6 p.m. on ESPN.
