I wouldn't be so sure about that. Getting the chance to actually watch Rick Nash play night in and night out, he's utterly dominant. Honestly, it almost seems like he's "slumping" scoring-wise and he still has 3 goals. He makes something happen every time he's on the ice and is very visible at all times.
In terms of being a Rangers fan, I don't think anyone will call you a bandwagoner. They haven't won anything yet, so there's no bandwagon for you to jump on. I think they're the best team in the league, though, so there's that.
