It's most likely going to be a retractable roof stadium like it or not. They aren't going to build a new stadium and use it for 10 games a year like the ralph. They will be a retractable roof stadium that can be used year round for all types of events which will make money for the pegulas, the bills and buffalo. This isn't the team of the 90s, they aren't some team that is good in the cold lol. Stadium will be open most of the time unless there's bad weather and will be closed during blizzards preventing all that snow getting into the stadium.
