Have we seen the apex of Hamilton’s arc?

Bill from The Daily Something wonders aloud about Josh Hamilton, his career arc, injuries and other stuff like that. So maybe I'm just preparing myself for what seems inevitable. That just seems like part of the story, like how Roy Hobbs...was fated to have his brief moment in the sun before injuries and age took the game away from him again. The plotline calls for a tragically brief flash of brilliance, not ten years of stardom.
