I heard it reported that there was interest from 3 or 4 teams (I think, from memory). I agree with Billsfan that I don't believe any of the big names were in the mix so he called it a day. The Jets were rumoured to be interested as a replacement for Edwards, but I'm guessing that fell through when they signed Burress. I don't think any of the other likely contenders were in the WR market, particularly given the 2011 cap, as I can't imagine Moss would play for free.
Shame he ended out playing for 3 teams (with no real positive headlines) in his last season.
