I don't really disagree with the idea that the rest of the division is weak. OTOH, the Sox are projected to be about the 6th best team in baseball. So while they may not be that good, I think they are good enough to win the division based on their own merit, not just on the fact that the rest of the division is weak. I agree that the FO will add another pitcher by the deadline.
As far as the playoffs go, the key is to get there first, which the Sox have a good chance of doing. Once there, anything can happen.
