Since I assume you are a FIB based off your username, have you taken in a game at Soldier field? Probably one of the worst stadiums I have ever been to for getting in and out of. Not to mention how ridiculous it looks. While you cannot compare Chicago traffic to Buffalo traffic, I feel like putting a stadium in downtown Buffalo would have similar consequences.
I agree with your OP stance. I would love to see them do a full remodel of the Ralph similar to what the Packers accomplished with Lambeau. Effectively starting with the worst stadium in the league and transforming it into one of the best.
