Reminds me of Tmac situation with the Rockets, where the team doctors say he is fine, second opinion from another doctor says he is fine, but he keeps searching until he finds a doctor that says surgery might help him. Maybe he is getting misdiagnosed, or may be he has a low tolerance for pain like Tracy. It was said at the time that the condition Tracy had that led to the microfracture surgery was common among nba players and most just played thru the pain.
