Schadenfreude

Here's a position-by-position comparison of the current projected Yankees and Red Sox for next year. Each position is classified as toss-up, leans, likely, or strong for one team or the other; these are electoral categories, but I'm using them anyway. Deal with it. The numbers are the player's approximate average WAR per season, either since their first full season or since something like 2003 if they've been around since the 90s.

Catcher, Jason Varitek (2.0) vs. Jorge Posada (3.5): Leans Yankees. They're both old, so I think both numbers are overestimates of their worth, but there's no reason to think Posada's moreso than Varitek's.
First Baseman, Adrian Gonzalez (4.5) vs. Mark Teixeira (4.5): Leans Red Sox. Obviously, it's an exact tie, but Gonzalez is trending over the last few years (2.9, 3.8, 2.9, 7.0, 6.3), and he's going to be moving from PETCO to Fenway.
Second Baseman, Dustin Pedroia (4.5) vs. Robinson Cano (4.0): Toss-Up. Pedroia's coming back from injury, and Cano's trending, but basically they're both MVP-caliber players.
Shortstop, Marco Scutaro (2.5) vs. Derek Jeter (4.5): Toss-Up. Scutaro isn't nearly the level of player as his opponent, for their careers. But Jeter's trending... down. No reason to think that changes. Heheh.
Third Base, Kevin Youkilis (4.5) vs. Alex Rodriguez (6.0): Likely Yankees. Sorry, Youk, there's no denying it. (Though Youkilis' WAR numbers will be inflated a little by a shift to third base).
Left Field, Carl Crawford (3.2) vs. Brett Gardner (2.8): Likely Red Sox. Crawford's been in the 4.5-range the last couple of years, and with that offense behind him... yeesh.
Center Field, Mike Cameron or Jacoby Ellsbury (2.0-ish) vs. Curtis Granderson (4.0): Likely Yankees. No denying it, Granderson's a better player than the other two.
Right Field, J.D. Drew (4.0) vs. Nick Swisher (2.7): Likely Red Sox. Swisher's just not all that good, when you come right down to it.
Designated Hitter, David Ortiz (2.5) vs. Marcus Thames (0.7): Likely Red Sox. Lest you think I'm overselling Ortiz, he was worth 3.3 last year.
First Starting Pitcher, Jon Lester (5.6) vs. C.C. Sabathia (4.0): Toss-Up. Their ERA+ for the last three years are both right around 140.
Second Starting Pitcher, John Lackey (3.5) vs. A.J. Burnett (2.0): Likely Red Sox. They're both trending down, but in Lackey's case that means he was average last year; in Burnett's, it means he was sub-replacement.
Third Starting Pitcher, Josh Beckett (3.0) vs. Phil Hughes (1.0): Likely Red Sox. If it weren't for the other guys, Beckett could be an ace; indeed, he recently was their ace. Phil Hughes... yeah.
Fourth Starting Pitcher, Clay Buchholz (2) vs. ??? (0): Likely Red Sox. Andy Pettite (2.5) is said to be retiring; if so, the Yankees don't actually have a fourth starter right now. And Buchholz is trending, having been worth 5.4 in his first full season.
Fifth Starting Pitcher, Daisuke Matsuzaka (2.5) vs. ??? (0): Solid Red Sox. Again, the Yankees don't have anyone, and Matsuzaka is not a fifth starter on a normal team. Hell, he's practically be the Mets' ace until Santana got back...
Closer, Jonathan Papelbon (2.8) vs. Mariano Rivera (3.5): Leans Yankees. Yeah, well, Rivera is better than Papelbon. Worse still, he's coming off, like, his best year ever, or close, while Papelbon just had his worst. But it's worth noting that Papelbon has a higher ERA+ for his career than Rivera, and much higher than Rivera's through a similar age, and after all he's over a decade younger. So who knows?

The total projected wins using these WAR numbers are 101 for Boston, 97.5 for the Yankees. Oh, actually, that was including Pettite, so taking him out the Yankees fall to 95 wins, 6 games back. Cliff Lee is only worth a 3.0 in this algorithm, so they need two Cliff Lee-level pitchers to make up the gap. The Red Sox are better than the Yankees. This is going to be fun.
