This sounds fake, but I remember when I heard about KG for Big Al, it was at a cookout from an accountant I know who works with the C's. It was a full 4 days before even a dribble of info came out so I sounded like a crazy person when I told Jeff the rumor.
So sometimes this DOES happen, but more often than not it would be someone with higher level professional connections (not that I have those), not someone who surfs blog forums.
Plus anyone could make an educated guess at those details...
