With the recent comeback of Andy Pettitte, Fangraphs writer Wendy Thurm wonders if a rotation made of recently retired players (Pettitte, Mike Mussina, Randy Johnson, Pedro Martinez, and Greg Maddux) would be better than the rotation in any team this year. She estimates that such a rotation would indeed be better than a Pirates rotation composed of Charlie Morton, James McDonald, Brad Lincoln, Kevin Correia, and Jeff Karstens (based on the top 5 starters in Fangraphs' Positional Power Rankings). I don't know whether to feel insulted that the writer didn't include Erik Bedard and A.J. Burnett in the comparison, or grateful that Jo-Jo Reyes likewise wasn't mentioned.
