You need both, but i think if i had the choice between great defense + average goalie vs. average offense + great goalie, I'd take the great defense. But it better be great, and I want an above average offense to go with it
At the top of his game, what did Carey Price win? I actually always thought he was a bit overrated, but he was arguably better than Niemi, Vernon, or Osgood. Or Kuemper.
I really want to say "build goalie out." Ideally both. But if I had to choose, then great defense and a goalie who will make the stops he's supposed to.
Carter Hart is probably actually that and not the star goalie. As Flyers fans, we've been goalie starved for so long that "competent and can steal a game" looks like the second coming.
