Randy's agent is using Adam Schefter and others to try and increase the market for his client. I believe they hope to raise NE's contract offer, especially since Schefter keeps bringing up the Packers who didn't really want him before. Moss didn't really seem to fond of the Packers organization (and some of the things they said to him during the 2007 offseason), when asked about their interest in him during his pre-SB press conferences.
So, I think Adam is just trying to create a story (the Packers as a possibility) out of nothing substantial. Maybe he's just trying to find something to talk about, but he could be doing a favor for Moss' agent. After all, most agents love Schefter, and give him contract scoops...
I honestly believe their hasn't been the kind of interest from other teams in giving Randy the huge type of blockbuster deal his agent (and others) have expected. Just think about it. He's 31, had some troubles in his past, and claims he wants to play with an established QB and for a contending team (that knocks a number of teams out of the market right there, lol) Also, look at all the other WR's who've already signed elsewhere, and for good money.
If some of those teams were all that interested in Moss, then I believe they would have at least offered him something, or set up a visit. It seems kind of funny we haven't heard anything about Moss visiting other teams, and there hasn't been anything but mediot/blogger rumored interest from other teams.
So, I think he wants to stay in NE, and will eventually stay in NE, but they are trying to create interest elsewhere to push NE's contract offers up a little.
