11. Josh Byrnes, Arizona Diamondbacks I'm not quite sure if the Diamondbacks are a team whose young players haven't developed as well as they should or an extremely young team that just hasn't come all the way together yet, not that these are mutually exclusive possibilities. Either way, Byrnes has done an admirable job collecting young talent and patiently letting it develop. The odd questionable move like trading away Carlos Quentin has been more than balanced out by savvy moves such as trading for Dan Haren. There's a championship team somewhere in this collection of talent.Sport Illustrated ranks our GM 11th.
