That's a close call. Phoenix is brutal and definitely brings that division down. But three of the top five teams in the league (Anaheim, Dallas, SJ) are all in the Pacific. Imagine being a team like the Sharks and having to play 16 games total against the Stars and Ducks? No thanks.
That said, the NE division is a little more balanced, top to bottom. Any game Buffalo has against a divisional foe is not a gimmie by any means and I think that could be said for any Northeast team.
After slow starts, Ottawa and Boston are starting to come on (Bruins have beat the Leafs twice in four days). The Habs look like they could be for real and Toronto is...well, Toronto. If the Bruins continue to improve as they have over the last three weeks or so, there's a shot that all five teams could wind up in the playoffs. Not likely of course, but they could all be in contention.
