Say what you want, but the reality is that the Canucks Defense corps as a whole is -22 on the season, with only Salo, Rome and Sulzer on the positive side. Their defense needs to be better, regardless of who the goaltender is.
Also, much like the Hawks, I still don't think they have the horses up front in the bottom 6 to withstand a significant injury, like Kesler.
They're also probably suffering from having short off-seasons for 3 straight seasons and a "Stanley Cup hangover", only without the Cup.
