To back up that point, the red sox scored 3 or less runs 30 times in the final 84 games for July, August and September. The Yankees did so only 21 times in that span. Thats a difference of 9 games of putrid offensive performance over a span where they were essentially neck and neck with NY for top offense in the game.
In that same span, the sox scored 7 or more runs 29 times. The Yankees did that only 26 times in that span.
Using those numbers and knowing that the sox did score less runs than NY in that same span (25 less runs to be exact), one could make the assumption that Boston was pretty inconsistent. They were more capable than the yankees of blowing you out, but also more capable of just being shut down. Now, consider their nature, remove Lowell, Bay, and Gonzalez and add in Scutaro, Cameron, and a healthy dose of Casey Kotchmann or Vtek depending on how you think the lineup is going to shake out.
