Where in any of those links does it say that the PA can look at the books of any and all associated businesses? Unless I missed it, you made that statement up.
BTW, Ted Saskin on McCown's (sp?) Prime Time (replay) on SportsNet just confirmed that he has access to things like arena revenues. He was even specifically talking about his ability to validate whether the Senators are making money or not. He also said that the same deal that gives him that information, also requires him not to disclose it.
