If you watched the Tampa series against Columbus, it was very much the same. It took Tampa 4 OT's to beat Korpisalo in the first game and they never were able to beat Columbus by more than 1 goal despite having games where they had literally twice as many shots. They could only score 1 goal in the 2nd game and lost by 2.
They were stifled a lot by Columbus as well, especially early on. But Vasilevsky outplayed Korpisalo and Merzilkins in the end. Andersen did not. In the first and last game, where we were shut out, Andersen gave up weak goals and then Columbus just sat back on their lead and tried to clog up our offense instead of having to push us. We had to push through 5 bodies consistently, and no matter how good your offensive team is, that is not easy. Especially when at the same time, Korpisalo is making ridiculous point-blank saves and stopping everything that comes his way. Andersen, meanwhile, can't stop a muffin shots from the top of the circle along the board with literally no traffic.
Our offense earned the benefit of the doubt. They were one of the best offensive teams in the league and were still generating a bunch of prime scoring chances that Korpisalo had to stop. Andersen lost that benefit of the doubt by being one of the worst starters in the league that year, despite a much improved defense in front of him, having a tendency to collapse in tense situations even when he was considered a top starter, and always getting outperformed by the goalie at the other end of the ice in the playoffs. Against Columbus, he couldn't even play as well as the defense in front of him, while the goalie on the other end played even better than his defense, which was also quite strong.
This year, it is no different. Outside of a couple of games, he has just played as well as the defense in front of him and Cup winning goalies need to be better than that. Fortunately for us, our defense is playing about as well as our offense right now, so that is good enough for us to be winning most games. It won't be enough in the playoffs unless our offense fires on all cylinders every game, but that has never happened even for the most talented offensive teams. There are games, or even series, where our goalie is going to need to carry us and I don't think Andersen has shown he can do that enough since his second Game 7 collapse against Boston.
I hope Andersen can do it for us this year, but he is by far my biggest concern with this roster right now. There are places we can improve on our offense and maybe even our defense (although I probably wouldn't touch our defense), but the biggest question mark by far will be Andersen and if it were possible to maybe quell those concerns, then the Leafs should probably look at it. For the second straight year, we are getting below average goaltending from Andersen.
