smaller stadium that is a Dome.
Dome's are not cost prohibitive by their nature. SU has one, Minny has one (I like that idea), DET has one, etc.
Make a 60K seat dome. Pack it, let the noise of Bills mafia run free.
Hopefully this stadium is built for a dome option. That, or quit putting home games at the end of the season. I mean, the Bills are trying to sell PSLs, and most of the games are in terrible weather which makes reselling even at face value impossible.
