I really disagree. In any given year, there's maybe a dozen teams that have a shot at the Cup.
Last year, LA was a favourite entering the season. New Jersey was the surprise. The year before, Boston was considered one of the top dogs in the East, Vancouver was top in the West. Chicago and Philly were both loaded when they went to the finals.
Really, there hasn't been an off the radar Cup winner since Carolina in 05-06, and they sank back to earth faster than the Titanic.
