If you think the Avs are the biggest disappointment, because they were supposed to repeat their success last year, go park yourself in front of a mirror for a good while and have a nice long talk with yourself about what you know about hockey.
Wild are the biggest disappointment by far and no one can take that away from us.
The Bruins and Jackets have been injury riddled, so they're out. Everyone knew the Avs would regress, for sure, with the unsustainable play and poor possession numbers. I mean, they have Holden, Redmond and Guenin, 3 AHL caliber d-men, as regulars heading into the season. That alone is cause for concern, so the Avs are out. Hell, people could see the Stars reasonably regress due to their terrible D as well, so they're out too. The Wild, on the other hand? They added Vanek for what was seen as a hometown discount (especially in the term department), as well as getting full seasons out of guys like Haula to add depth scoring, it was reasonable to expect the Wild to be the 3rd/4th best in the division on paper, even with the question marks in goal.
Even though I'm a Leaf fan first, I've always really liked the Wild and do root for them whenever they don't play the Leafs or Sharks, but I don't really know how anyone else can be a bigger disappointment than the Wild this year, unfortunately.
