Moss is being held out by an extra-cautious Bill Belichick, who has the luxury (and the faith in Moss's talent) to wait, given how many other damn WRs he needs to decide on right now.
It's amazing to me that something as plainly obvious as this can get past the media, who seem to be far more focused on what may be a better story - Moss is dogging it! - than the truth. While I suppose I "get" why they want to go in that direction, it's just setting them up to look stupid in the end, being on the wrong end of "I told ya so."
