Per
ESPN, Colangelo and USA basketball have until July 8 to submit a 12 man roster. Additionally, the James Harden was also added to the 18 man group. The rest are Kobe, LeBron, Carmelo, Wade, Bosh, Love, Chandler, Paul, Williams, Griffin, Iguodala, Durant, Gay, Westbrook, Odom and Eric Gordon.
I didn't realize it was a USOC deadline and not a FIBA one, so it isn't surprising that the extension was granted. Barring injury, I'd be surprised to see Harden as part of the final 12, but wouldn't mind seeing Davis as part of the London team. Even if Davis is used like Boozer in 2008, it couldn't hurt to have a 12th man at a potential position of need.
