The thing about Moss is that he's so undervalued right now. You might be able to get him for a 2008 fourth round pick, moving upward conditionally.
I still don't see it happening, because Moss would have to agree to rip up his contract and sign another one that would allow BB to cut him without significant cap penalty if he poses a problem.
Would it shock me if this played out as another Dillon situation and we used Moss for a year or three? Absolutely not. As long as he realizes he's not catching 90 balls in this offense, and as long as Rodney's around to punch him in the mouth (and I mean that literally) if he gets out of line, Moss to the Patriots could be a mutually beneficial short-term proposition. Brady gets a reliable target who can take over a game, and force defenses to account for him every play, Moss gets an opportunity to be part of a winner, and rehabilitate his image so that in another couple of years some other team (Redskins, I'm looking in your direction) will be willing to offer him one final fat contract.
I'd be surprised if there wasn't at least something to these reports.
