I'm a journalist, occasionally cover sports. This guy is lying, I think. I love reading his posts, but think about it. The people who actually work at pro sports teams (and I've met a lot of them) think fans like us are pretty much the lowest form of life on the planet. Not only are we completely stupid in their eyes, and total amateurs when it comes to understanding their profession, but they all have had experiences in which talking to outsiders has resulted in something bad happening to them on the job. That's true of players, coaches, executives, all of them. The only (rare) exceptions are guys like Curt Schilling who really never outgrew being sports fans themselves.
Anybody who would do something like this on an ESPN message board would be putting a gun to his head every time he sat down and typed. If BB and Pioli get wind of it, and he makes one slip -- misspells a word the same way he did in an internal memo, say, or repeats an opinion that maybe he's had at work -- and the guy is blacklisted from sports jobs forever. Who in his right mind would do that? The odds are overwhelmingly against it. On the other hand, there's a ton of incentive for some dweeb in his basement to try to pass himself off as an "insider" who hangs around with the Patriots coaching staff by day. It happens every year in every sports team. Last year there was a guy calling himself "Celtic Thug" on Cs boards who kept telling people he knew of an impending sign-and-trade deal for Rashard Lewis. He was lying. It's very common. I think that's what's happening here.
