ESPN is reporting that the New York Yankees have signed free agent first baseman Mark Teixeira. Add up Teixeira's contract with the offseason signings of A.J. Burnett and C.C. Sabathia and you have $423.5 million in guaranteed contracts. Pretty amazing, huh?

Sure, the Yankees have contracts that come off the books, but that's not the reason why the Yankees can do this. The reason the Yankees can do this is because their owners, the Steinbrenners, have no other primary business besides the Yankees.
