That’s an incredibly misleading stat. Ullmark played one game and came in another after Swayman was yanked. The year before Ullmark was outstanding for the first 4 games but for some reason Monty decided to go away from the rotation and overwork Linus.Swayman also had a very, very strong .933 save percentage in the playoffs last year. Ullmark was a horrible .896 and .886 the last two years in Boston in the post-season.
If you’re gonna blast Ullmark for his brief playoff stint this past year then you have to do the same for Sway the year prior.
