It would be interesting to see what the "oddsmakers" predicted for NHL teams over the previous 5 to 10 seasons to see how accurate they were. I'm sure they're right more often than not, but I'd guess they've had their misses as well.
Having Demko healthy will do wonders for the goals against. Last season, even before Demko went down to injury, he just didn't look right out there. With the additions the Canucks have made, the PK should be much improved as well. This year's team just seems to be better constructed than the teams we've iced over the previous few seasons.
