Nah, unfortunately, I just saw a tweet about it. I’d love to see more, too, and see what defines a game as stolen or lost. He did also say:
Steal % (min. 25 starts)
Ullmark - 20.0%
Dostal - 18.2%
Gustavsson - 17.0%
Edit: it looks like steals may be when the goals saved above expected is grater than the goal differential in a game.
Found a stat for it from 8 days ago on Reddit, so these are a little outdated.
Gustavsson had 9 steals, 2 blown, +7
Dostal had 8 steals, 3 blown, +5
Helle had 6 steals, 1 blown, +5
Wolf had 5 steals, 0 blown (!!), +5
Lankinen had 2 steals, 7 blown, -5
Vasi had 4 steals, 9 blown (!!), -5
Elvis had 2 steals, 6 blown, -4
Soderblom had 3 steals, 7 blown, -4
