On this Red Sox vs Yankees thing, it has ALWAYS been about pitching. Even when the Yankees had Raschi, Reynolds and Lopat, and the Red Sox had only Parnell. The Yankees always have hitting, but their pitching slipped early in the decade because they signed too many older FA pitchers and didn't develop any studs in their farm system. They won this past year because of Sabathia and, in the playoffs, Burnett.
The Red Sox suffered mainly last year in their starting pitching. The horrible starts of DiceK, Beckett and Lester plus all those gambles Theo signed that failed. What saved them early from worse was Wakefield. I don't expect the pitching to get off to a slow start this year.
I would add that Francona may have to play some small ball this year on the road, which he is not used to. They were not good on the road last year, but their pitching wasn't that good to compensate for the expected dropoff in hitting. Francona is accustomed to sitting back and waiting for the hits to fall, but that could change if they don't add any more hitting.
