18. New York Islanders
One of the worst attended teams in the NHL, sometimes you just have to ask what’s the point? Who goes to Islanders except for people who want to experience a hockey game but can’t get Rangers’ tickets? Who loathes their children enough to doom them to the fate of following this grim franchise for the entirety of their lives? Sure, they won four straight Stanley Cups from 1979-1983, but that was back when the drinking age was still 18.
The Islanders do make the playoffs but there is rarely any danger of them doing anything dramatic. Meanwhile, their state rivals, the Rangers, are the most valuable franchise in the entire NHL. In sum, if you love hockey then you’re probably going to support the better team unless you’re actually from Uniondale. Like the Mets who come next, it’s tough to be in the shadow of a bigger franchise. That’s a tough mentality to shake.
