Skinner sucked on two important goals tonight. You don’t need stats for that. And even if he saved another 40 perimeter shots it wouldn’t compensate for his errors (even if the stats said it should).
But xGA or GSAA are horribly flawed. It can’t tell you anything about an east west pass to a one timer or to a tap in, or even a breakaway… it’s literally a static measure based on type of shot and location. You could put Ovie in the high slot with a bucket of pucks and have him snipe from a static “high danger” location and an average level EBUG will stop 8or9/10.
It’s the movement and the getting there that matter.
GSAA Ihas zero to do with real-life goaltending because it doesn’t have the capacity to consider the things that make goaltending hard (or easy).
Never seen a goalie coach or goalie argue its merit because it’s so fundamentally flawed it’s comical.
