Interestingly enough, there are some really good players who are available for the right price, ie. Adrian Peterson, Hakeem Nicks, Larry Fitzgerald, Jared Allen etc. Perhaps if Doug Whaley where to consider this an extension of next year's FA period, we might be able to pick-up a player in a Byrd trade that could help the cause. However there aren't any notable OL or DB players being talked about and the cap hit for another top WR or DE wouldn't make much sense.
My guess is the Bills will not be players this time around.
