I voted for the Flyers simply because of the strength of the Celtics this year. I don't see anyone beating Boston in the Eastern Conference playoffs. I don't follow hockey that much but it does kind of seem like the NHL Eastern Conference is up for grabs as there's not really a single dominant team (the 8 playoff teams finished within 10 points of each other).
I picked the Flyers because I just don't see ANYONE from the East beating the West rep in the NBA Finals, whereas there is at least some balance the the NHL.
Right now it looks like the Sixers if they can stay consistent. I think that the Flyers have a more realistic chance though. If it werent for us screwing up Game 1 we would have great momentum against the Canadiens.
