I think new stadiums and price increases improve fan behavior for a variety of reasons. Expect the new Bills stadium to do the same. However, talk of “pricing out” poor behavior always makes me chuckle. People are aware that white collar professionals aren’t the only people who make good money, right? Stadiums in east coasts cities like Boston and NY are always full of clowns, because it’s part of the sports culture. It might be different in other areas of the country, but it’s more a regional phenomenon, opposed to an economic thing.
