Feel like ATL has the better star power while NE is more defensively responsible in their forwards. SE isn't far behind in either.
Defencemen NE wins, followed by ATL then SE
Goaltending is given these players, ATL kind of by far. Give Anderson on the NE and it is closer (since we are assuming magical healthy times) but ATL still wins (Brodeur has been amazing this season, as per usual I guess). SE isn't bad, just Ward isn't as good as he normally is from what I've seen.
Final vote probably to ATL but I feel if they were to play each other NE could come out the winner due to defensive ability. SE is always going to be perceived as the weakest, but they really aren't that far behind.
