I think a Castro signing would be quite apropos for the Sox. It helps them reach out to the student population that buys Che Guevera shirts, one of the few untapped revenue streams. They can hoist banners across Fenway saying "The AL East is Red." Larry Lucchino could call a press conference, take off his shoes (in the process revealing his Red Socks) and bang them against the table while denouncing Yankee Imperialism. They could even get access to Cuban baseball players, without the trouble of them defecting. This move would also pave the way for favorable relations between Red Sox Nation and the Chinese government.

Boras has this idea that ARod generates more revenue for a team because he's such a media fixation.  There is some truth in that, but I don't think it's $350M worth.  Also, I know baseball teams are businesses, but if you had two players that you could sign for the same money, but player X would generate more revenue while player Y would win more games, who would you sign?

As fans, we would say player Y, but I think for baseball owners it might come down to "how much more money?"  I think in the long run, an owner who isn't perceived to be putting the success of his team over other considerations is going to lose a lot of potential revenue.
