I would guess that it has everything to do with the opponent. The Senators are not a high profile team, the casual fan doesnt know much about them or any players on the team. And New York is expected to romp them so its not getting the attention it normally would if it was a tougher opponent. Oh and they are Canadian and they are not one of the sexy Canadian teams (like the Habs, Leafs, Canucks), so that immediately turns off some American fans. I would expect to see the attention to ramp up for them next round. The series itself is quietly interesting. Some of the time, NYR clearly looks like the much more dominant team, but at other times, for whatever reason they struggle. I don't know if its NY taking them lightly or what, but if they lose this game (about to go into OT), it could get interesting. I'm pulling for Ottawa myself, their coach used to coach my area's minor league team and he has a cool mustache.
