Curt Schilling's rough outing today speaks to a larger point: the Sox may have rotation concerns. Schilling may still be effective, but he's 40 years old. Josh Beckett is roundly overrated and ill-suited to pitch in a park like Fenway. Dice K has ace stuff, but he remains a bit of an unknown quantity. Tim Wakefield is a notch better than league average these days, and the fifth spot is going to be a serious concern now that Jonathan Papelbon is in the bullpen. In other words, much depends on Schilling's ability to pitch something like he did in 2004.
