I'm fine with the goaltending. Not really impressed but not unhappy either. Luongo will likely end this season with solid numbers but I don't get the feeling he can be a game stealer anymore. You just know that if the team gives up those prime scoring chances they'll probably go in, even if it's not Luongo's fault. I also like the look of Lack. Not surprised, though, as something this organization has proven is they can spot and develop great goaltenders.
I'm really happy with the defense. They look much steadier than last year and certain individuals, namely Bieksa, have improved under Tortorella. Garrison and Edler have been more average lately but I don't think you can point to any one defenseman on this blueline and say they're playing bad and that's a very good sign.
My issue lies with the offense. First of all, you have the question of whether or not the Sedins can produce against the biggest, best teams in the West but that's another topic for another day because they're generally one of the best lines in the league and they are showing they are still PPG players at this point. Kesler has played really well with the Sedins but we still don't know if he can be an offensive force on his own line where he really should be and therein lies another issue: depth.
Kesler on the 1st line leaves Santorelli centering the 2nd line along with Higgins and Burrows on his wings. I don't care what anyone says, that is not good enough for a team that wants to contend. A lot of great teams have a big 4 on offense (Chicago: Toews/Kane/Hossa/Sharp, San Jose: Thornton/Marleau/Couture/Pavelski, Los Angeles: Kopitar/Carter/Richards/Brown) and the Canucks really only have a big 3 in Henrik, Daniel and Kesler. It's clear Burrows is a great complimentary player but he's not going to help drive the offense.
What the Canucks need is either a bonafide top 6 centre if Kesler is going to remain on the 1st line or a top 6 winger to play with Kesler if he's to return to his normal 2nd line centre position, which I think is better for the team, despite the success of the Beast Modo line. The current setup has worked through the first quarter of the season but in order to compete with the Kings, Sharks, Ducks, Blackhawks and Blues of the world the Canucks need to be able to roll the Sedin line and the Kesler line, not the Sedins and Kesler on one line and the....Santorelli line.
Anyway, I'm kind of rambling about the offense issue but the TL;DR version is: the Canucks need another bonafide top 6 forward to help with the offense. This will also help other issues, like the PP. Other guys will then play in their rightful positions where they can better play within their means and the team will function so much better overall.
Quick note on special teams: Very polarizing aspect of this team. The PK has been great, the PP has been awful. I don't think you can get more polarizing than the best PK in the league and the 3rd last PP in the league. As I said, though, picking up another top 6 forward will greatly help the PP I think. Imagine grabbing someone like Lecavalier or Voracek from Philly and putting them AND Kesler on the 2nd unit and putting someone like Kassian on the 1st unit, knowing the Sedins will hopefully figure out their PP woes soon, regardless of who's with them on that unit. Talk about two dangerous units.
