In response to dustcover's comment:
Looking ahead a bit, here's what the New Yorker's lineup may look like. Remove from the equation their pitching and depth, how productive will this lineup be?
Gardner LF LF
The outfield looks solid, as does McCann at catcher. The infield is potentially one big clusterbeep. As Hugh said, this team is very hard to predict. They could be quite good, they could be very bad.
The lineup will almost surely be better than last year's line up. The question is, how much better? They were 10th in the league in runs scored last year with 650, 50 fewer runs than the 9th best team and 203 fewer runs than the Sox. They were 13th in the league in wOBA (.301) and 13th in OPS (.683). So, saying that they have improved offensively, even saying that they can potentially improve at 7 of the 9 positions, isn't necessarily saying a whole lot.
Personally, I think they fare better overall with their rotation than they do with line up. That said, there are a lot of question marks with their SP that could go either way too.
