I agree with you on the goaltending. Regarding the forwards though, since Yzerman assumed EGM duties for the 2010 OGs, Canada's forward group has been built from the center out...with the wingers (Iginla, Nash, Richards, Benn, Carter, Perry, Marleau) usually being fast (well, maybe not Perry), physical, defensively responsible, and good goal scorers. Any centers that were converted to the wing had played wing at some point before, and the remainder were natural wingers. There are no players of that caliber or style available at this point, besides someone like Marchand, Stone or Stamkos, who are all getting up there in age, or maybe Scheifele or Dubois (if converted to the wing). That's a bit of a dropoff, barring someone like Kyrou or Lafreniere continuing to step up their games this season.
The forward group, for the first time in a while, will likely be comprised of mostly centers and some playmaking-oriented wingers like Marner and Huberdeau, which can come with line formation challenges. Maybe not so much on NHL-sized ice, and of course our centers are outstanding, but something I'll be keeping my eye on.
