Well, last year they had decent defense (blue line turnovers just killed them however) and the goaltending is as good as anyone's in the West.....so all they really needed is more goal scoring.
Now they have that in Heatley and Setoguchi, to go along with guys like Bouchard and Koivu.
They haven't looked all that hot in the early going, but I expect them to get on a good run sooner than later.
