It seems that the outbursts by Boras and Henry have pushed the PBC to "open" their books. DK reports that the club made less than $11 million over the last two years. In a pointy-haired boss-like statement, Cooneley said, “"The Pirates utilize every dollar we receive in our effort to build a winning club." The article suggests that Boras was high by about 12% and Henry was displaying cluelessness.
Assume for the moment that this is true. It probably means that there are a lot of clubs with troublesome bottom lines, since quite a few have some silly contracts out there.
