How are the BIlls supposed to stop two other NFL franchises from completing a trade? They can't stop the Jets from trading for Aaron Rodgers. They couldn't stop the Dolphins from trading for Hill. If the deals are similar, I would think that the Cardinals would go to Hopkins and ask him for his choice. He would probably choose KC because
He would be WR #1
Better chance to win a SB on the defending SB champs
Wouldn't have to deal with 70-inch snowstorms.
Sure, the BIlls could probably get Hopkins right not for Oliver and #27, but that would be a massive overpay. Is that what you want Beane to do?
