Not sure how valid these are, but take a look, both are pre-luxury tax.

Personally, I'm not exactly enamored with the Sox ever-growing salary, particularly as it hasn't turned into results. I think it's moderately embarrassing for either of these teams if they don't make it to the playoffs in a given year, but much more so for the Yankees.
Even with their bloated payroll, the Sox are still 70 mill behind the Yanks. Teams like the Twins, Orioles, Jays, etc., hover around that 70 million payroll as is. It's just such a huge advantage.
If the Sox had that 70 million to spend, that could buy you (2006 salaries of) Albert Pujols, Carlos Beltran, Vlad Guerrero, Roy Halladay, Roy Oswalt & Johan Santana. Just gives you a little perspectve on the kind of advantage the Yankees have, and what a joke it is that their team fails to win the world series with their payroll.
