Thought you guys would appreciate Baseball Prospectus's reasonably complete analysis of Josh Byrnes's tenure in Arizona, though I think most of us will disagree with the classification of the Haren trade.

Bottom Line

In answer to the title question, the Padres are getting in Josh Byrnes an experienced GM who has a strong trading record (and who is aggressive in dealing when his team is poised to make a move) and a decent drafting record (few stars, but some useful pieces), and who once made a terrible decision regarding two outfielders headed in opposite directions. Padres fans will be interested to see whether Byrnes has learned from that mistake, as one of their former GMs (Towers) learned from a similarly terrible decision regarding Randy Myers that hamstrung his club for a while.
