plus, there's some weird loophole deal relating to the shared revenue plan, where baseball ends up paying for a certain percentage of a new park if you meet certain requirements... or... something...
i don't remember the details, but i remember that it meant mlb would have to pay some of george's bill.
whatever the deal, bottom line is the yankees are paying for the entire park, which is like a 6-700 mil deal. new york's 200 mil is going to a massive area in the bronx around the park -- as well as enveloping the current (and then old) yankee stadium, for public use.
