I was actually awake for the beginning!
I'm still waiting on the NFL to come out with a report of some sort. Speculation based on speculation is risky business but that hasn't kept the media, mainstream or otherwise, from running with every "sources say..." they get.
Belichick's Saturday presser was essentially a "Put up or STFU!" message. He's either very confident that they'll find nothing or he's providing the noose for the hangman.
