Been wondering the same thing for a few years, jimk. I think I’ve got it figured out now.
I believe that it’s entirely driven by the high-profile guarantee games. Last year, I think the ‘nova game was the holdup. At this point, I suspect that it’s UVA. I think it’s probably part of the deal – we can announce those games when “daddy says we can”. Seems like this is what we heard though 6-degrees-of-separation info on the ‘cuse game this year. I’m betting we can’t announce until UVA does.
