We've seen National Hockey League teams restrict tickets access to outside fan bases when they're battling for the Stanley Cup, but it's not a common thing to do during the regular season. In fact, it doesn't make sense to restrict ticket sales during the regular season. That won't stop one NHL team though.
Again, restricting access to tickets for fans outside of Buffalo doesn't make any sense, honestly, it sounds like Buffalo is whining about the state of their team, instead, they should try building a winning team and finding players that want to not only make the playoffs but go far.
