I think people have trouble comprehending the fact that Rangers fans get angry and boo vs. ending support for the squad.
Rangers fans get frustrated because we expect the best. For most of our history, we haven't gotten near that. Especially over the last two decades, where we bring in all these high end players and they just fall off. The worst is when we feel players/teams aren't giving their all. There have certainly been times this year where I've felt that way with this team. Last game was not one of them.
People should not confuse expectations for loyalty. This is one of the most loyal fan bases in American sports. I expect this team to give 100% night in night out. If I dont' feel they are, I'll be pissed. Never will I turn my back on them though, unless something severe happened.
Edit^^ Bandwagoners are not fans. You'll get the bandwagon when a team makes the finals, especially in a place like NYC. That being said, the real fans of this team, of which there are a ton, really don't waver much.
