So basically the Red Sox added some role players to fill out the secondary roles in the lineup while the Yankees added what basically amounts to the core of the team?
Drew was a sub .800 OPS hitter, Lugo below .650, and Matsuzaka a pretty decent #3.
Teixeira was a .950 OPS hitter, Sabathia a 19 game winner, and Burnett a solid #2/3 pitcher.
I don't think there is really a comparison here.
What the Red Sox did would be comparable to the Yankees adding Damon, Pettitte, and Swisher (you get the idea, good but secondary players).
What the Yankees did would be equivalent to the Red Sox adding Manny, Beckett, and Matsuzaka.
Again the Yankees basically bought the core of their team
