Look, he went to UT like most of the rest of us. He hung around some of the people in the journalism dept and that gave him access to some of the people in and around the athletic dept. He's held onto some of the relationships and some of the people who know some of the people and so on. But you know, a lot of his stuff just comes from chatter from those folks and some from people like us. Then, he goes on the air to break the story and, kinda like a kid who is trying to fabricate a story, gets all tangled up in what he knows and what he thinks he knows. I remember I posted something on here that I just guessed at (and spelled it out as such) and thirty minutes later he was speculating about it on the air. Callers were calling in twisting it a little more and soon it was what I would call a bunch of nonsense.
Anyway, he does have a great show if you listen to all the characters. Don't expect to hear anything there first because chances are we've already broken it down here.
As far as X, who knows. I think it is him. I think he has access to somebody close to the department and gets some info there as well as TOS.
Also, for what it's worth, I think some of the people he "has" in the athletic department get kick out of some of the rumors they start just for fun.
