Johnson is uberquestion mark, Pavano not so much but still a question. Who knows if Small can repeat in any way at all resembling his 05 performance, same goes with Chacon, and there's not much of a bullpen in the long relief. Their lineup is good, but it's still very top heavy.
Conversely, the Sox don't know about Schilling, the shelf-life of Beckett, whether Clement will ever function post ASB, or what performance if any we'll get from Foulke, Lowell and A-Gone (whose "A" may stand for "Already"). But we have Papelbon and people like Meredith, Alvarez (though not as likely as), Hansen to fill in holes that might pop up and Snow, Youk, and Choi for those infield questions (granted that Snow may be as big an offensive liability as Gonzalez.)
Crisp has potential to be, ahem, the next Johnny Damon (tongue in cheek), and Damon was a question mark for us for a lot of 05, despite his many hitting streaks, and is already looking like he's on the same track.
So while we may have the same number of questions in our starters, our questions are not nearly as imposing and we already have a number of answers prepared, whereas the Yanks have very few contingencies.
