You hammer Beckett because he moves from the NL to the AL and his ERA shoots up a run or so, but Arroyo makes the opposite switch and his ERA plummets yet you are talking about him being gutsy, and coming back to earth?
Hypocrite. You can't have it both ways. The NL/AL switch is a considerable factor (in Beckett's case, a negative factor) because he's moving in the tougher direction as opposed to Arroyo (a positive factor). Arroyo didn't get any better, he's still the same old average 4+ ERA AL pitcher that he's always been, its just that his competition is considerably weaker. There's no way in hell Arroyo would have the amount of wins and ERA he currently has if he was in Boston. Stop making it sound like the guy has transformed into an All-World pitcher.
