Don't worry, it's his pathological response taking over. When it comes down to brass tax, he's admitted, every time, that the Red Sox can't compete financially, not dollar for dollar, with the Yankees. Yet, despite his previous admissions, he can't resist the temptation to deflect attention from the elephant in the living room (Yankee spending).
The reporting on revenues is out there if you are willing to search. It's unquestionable that the Yankees earn to a degree that allows them to spend as much as $80M more than the next team with ease. Estimates of the revenues generated by the new Yankee Stadium only increase the discrepancy. If anyone is going to question "desire" to spend as it applies to profitability, then it should be Yankee fans questioning why they didn't pick up both Lackey and Holliday this offseason.
