Apparently, USA Today (which cites the oft-quoted E.J. Borghetti Twitter thing)thinks this all got started with a post by Ben Maller, radio host for Fox Sports. His post, though, didn't come until after the recent message board explosion and of course, no sources are quoted.
Chicago Trib says nothing to the rumors, according to 'a conference source.'
Third parties are chiming in, too, mentioning a Big Ten expansion could open the door for a non-BCS school like Memphis.
Apparently, The Big Ten, when asked about it, has offered the obligatory 'No comment.'
I'm assuming that Pitt isn't coming out and definitively saying it's not happening this week in order to keep the obvious follow-up questions (i.e. if not now, when) from being asked as they anticipate they could be one of the schools in the running. But if the athlete meeting, which appears to have taken place (though no one is sure of the susbstance) really WASN'T about the Big Ten, why wouldn't athletes say what it was about?
Anyway, there's also the talk out there that Pitt will be leaving later, just not now. Although, no sources on that, either.
ADD ON: Missed this earlier, but Bob Smizik of the PG also says the Big Ten was not mentioned at the recent athlete meeting.
