Considering how bad their receivers are and how little he's getting paid, even if he stinks the Pats can sit him for a game or two and get back a 7th round pick and lose almost nothing. I think there's definitely a decent chance that he adds very little to the team that couldn't have come elsewhere, but the cost is still very low. And as I noted above, they can have him for a minimal investment next year as well. The only way this really doesn't work out for them is if he costs them game(s) with lunacy on the field, in the locker room, etc., and that seems unlikely given that team and that coach. Albert Haynesworth didn't work out for them on the field, but he didn't cause any trouble, so the only cost was a fifth-round pick, just as would be the case here.
