I don't know, it kind of feels like comparing apples to oranges. If Mussina wins 20 and A-Rod is constantly hitting into double plays in big spots, it's difficult to make a case for A-Rod. But during A-Rod's MVP season he was, of course, pretty valuable.
Bottom line is, I think the Yankees did the right thing this year going after the best pitchers, and not the best hitters. You can argue Sabathia and Burnett aren't worth the money, but hey, Brandon Webb wasn't available. They did secure the best and second/third best starters on the market.
If they would have signed the best hitter available, Texeira (Manny falls into his own category), and left the pitching staff as is....that would be ugly.
