Fair point, and one I've been contemplating since the season ended. Lets compare the lineups.
2009 Yankees:
Jeter
Damon
Teixeira
Rodriguez
Matsui
Posada
Cano
Swisher
Cabrera
2010 Yankees:
Jeter - Expected regression
Johnson - While he's not the same caliber offensive player as Damon is, if he can stay healthy, his OBP will be a huge asset in the two hole, and his power numbers should improve at NYS. It might be a slight
downgrade, but I don't think it's too big a deal.
Teixeira - I expect much of the same.
Rodriguez - A full season out of A-Rod (if they get that) would be an improvement over his output in 2009.
Granderson - To me, he's a big mystery. It's unrealistic to think that he'll produce at level that Matsui did in 2009, but I think it's possible that he has a very good season. I also think it's possible that he repeats his 2009 production. I honestly don't know, because his numbers the last three years suggest a lot of different things.
Posada - While he might show signs of aging, if the Yankees give him adequate time at DH, I could see him putting up similar numbers.
Cano - Huge mystery. If he really started to figure things out last year, and his ridiculous splits with RISP even out, he could be in for an improvement and a huge year. However, when it comes to Cano, you never really know what to expect.
Swisher - Expected regression, with the caveat that his home numbers should spike this year.
Cabrera - I expect much of the same.
I think they probably won't be as good as 2009, but I think it's still an offensive that can do a lot of damage, and there is probably more flexibility than last year.
