Lets just say for the sake of argument that the Bills get sold and moved to LA, so Miami and the Jets and New England will have to Fly to the west coast to play a game with another AFC East team ? I think not! I think the league will reshuffle the teams. Moving the Charges form San Diego Makes more sense, they are already a west Coast team, they wouldn't have top change divisions, and The L.A. Chargers make more sense than "LA BILLS" While the Folks in San Diego may not like losing "The Bolts" I don't an east coast team is gonna move everything to the west coast.
If the Bills move anywhere I think Toronto makes more sense, they can play in the Rogers Dome, until a new stadium gets built, Toronto is only 2 hours from Buffalo and many fans will make the drive into Canada, (Many wont also). The NFL would have a beginning of expanding into Canada and The Bills wouldn't have to change divisions. I could see in say 10 years the NFL buying out the Canadian Football League.
