Yeah everything is great until your goalie shits the bed in the playoffs...but what are the chances of that happening?That'll happen when you have the best goalie on the planet
People talk about it like it's a bad thing because it's not how they think we should win
"Top line HAS to win it's matchups", they'll say
Anyway, solid goaltending is a piece of the puzzle, but it's not the only thing. And it can obscure some more fundamental flaws if management's goal is, say, just make the playoffs and hope for the best.
You're not a true contender until you have enough to overcome your weaknesses elsewhere - and few teams win the Cup with obvious weaknesses (like a 1st line that can't outscore its opposition).
