Given Korpisalo's experience, it's undoubtedly a step down from their elite level play after dealing with Jeremy Swayman and
Linus Ullmark for the previous few years. With a terrible .890 save percentage the previous season with the Ottawa Senators, Korpisalo gave up one of the worst save percentages in the NHL. However, he will play with a much better team in Boston, so perhaps he can recover and find his touch from 2022-2023, when he put up a .917 percentage between LA and Columbus.
