Watch Cole in the replays of goal #1 and #3 and explain to me how that is good NHL defense. That's miles away from "not perfect defense".
I don't expect perfection from Vasy, and I expect even less from Cole. I do expect Vasy to make the occasional save when the defense lets him down. And we would all be a lot more forgiving on those goals if the other goals weren't complete gifts.
The defense hasn't really been a problem because it's been a lot better than Toronto's defense. Goaltending wouldn't be a problem if it was a lot better than Toronto's goaltending, but here we are.
