In response to RedsoxProspects' comment:
As of right now, we still have an edge but the Yankees are probably not done either. We will see in the coming weeks.
True enough. If they add another top SP'er and convince Jeter to move to 3B to make way for Drew, I wouldn't bet against the Yanks.
As it stands right now, I like our chances better. I think the Dodgers, Tigers, & Cardinals are better, and a few other teams about equal with the Yanks.
