I have the same feeling. We are entering another timeline in Habs Goalie land (Wamsley, Penney, Thibault, Huet) ....Other - Goaltending.
And I'll freely admit I'm biased...or at least, conditionned to think like this as a Hab fan. But as far back I can remember following this team, we've always relied on exceptional goaltending to manage anything. This was true with Roy....than Theodore in his run where he got the hart....Halak got hot in 2010...and Price was great for his career.
So for me - it feelds weird being able to do anything without stellar goaltending. So I think that's what's missing the most.
Not sure Montembeault or Primeau are good enough.
The D will have a "I need to cover, else he might not make the save" thinking...
