I think it's between Pittsburgh and Washington in the East.
In the West a number of teams could get to the finals. I have no faith in San Jose or Vancouver to go the distance. Detroit seems old, Phoenix can't score enough.
IMHO The rest just aren't good enough and would need luck or unexpected, over the top performances from key players. Which happens. For example I see Phoenix and Buffalo as wild cards because of their goalies and D. Detroit and Ottawa because of their coaches.
