I would have to think it was either the Packers or the Broncos, as Phinisher mentioned... May be more likely that it was the Broncos considering they reportedly were bidding on him up until the last minute in FA, so they may be willing to pay him what they would've given him otherwise, plus Fox is familiar with him.
Yeah, I hate that we're even considering this, if its true. As bad as his contract is, we'd only be compounding the mistake if we let him go. The bigger mistake was re-signing Stewart after sigining Tolbert in FA, which gives us two RBs with similar skill set.
With that said, if DW is traded I certainly hope we get the best value for him and he goes to a contender.
