Remember...the Yankees significantly outspent the Red Sox each World Series-winning year (as well as other years).
[table] Year | Red Sox | Yankees
2007 | $ 143,026,214 | $ 189,639,045
2004 | $ 127,298,500 | $ 184,193,950 [/table]
If money truly doesn't matter to John Henry et al, one is forced to wonder why they don't spend more of it, given that the Yankees are certainly spending more of it.
