That's way too simplistic of a view. Hockey is a very fast paced, dynamic game and to expect perfection of any one player is unrealistic. To expect that a team with better players isn't going to get better scoring chances, drive more turnovers from the other team, get more odd man rushes, etc..over the course of 60 minutes, is again, unrealistic. Alex Ovechkin is going to get really good shots against most defensemen in the league. The same goes for a goalie. It's unrealistic to expect them to stop every shot, even when fans think they should. In that light, you HAVE to expect that sometimes a goalie is going to make-up for a bad play by the skaters, and conversely, that sometimes the skaters are going to make up for a bad play by the goalie (ie...clear a juicy rebound out of the crease, save a goal, etc...).
So to say that the goalie can never be blamed when there is some sort of breakdown, is way too simplistic and I don't agree with. There are cases where both a goalie can play it poorly and the skaters can. Take the 3rd goal given up by Lack. The defense gave up a 2 on 1, so a breakdown. Then on the shot, Lack stopped it, but didn't play it well and the puck was loose, but then the Canes skater left the FLA player free in front to tap it into the net.
There's a classic case where there were two obvious defensive breakdowns (2 on 1 and then later not covering the guy in the crease) and a poor play by the goalie. You can't hold the goalie harmless on that one just because there was a defensive breakdown.
