Davis led Kentucky to the NCAA championship, winning the Most Outstanding Player award at the Final Four, and is expected to be the No. 1 pick in the NBA draft. Harden, a guard, is one of the NBA's top sixth men.
The final roster has to be selected by June 18.
The remaining healthy finalists are: Kobe Bryant, LeBron James, Dwyane Wade, Chris Bosh, Kevin Durant, Carmelo Anthony, Chris Paul, Deron Williams, Blake Griffin, Russell Westbrook, Tyson Chandler, Kevin Love, Andre Iguodala, Rudy Gay, Eric Gordon and Lamar Odom -- though Odom's status is uncertain after his poor season that resulted in the Dallas Mavericks deactivating him.
