hey hanrahan!
It's for a few reasons, he heavily tapes his left hand and wrist (glove hand) to provide more rigid support when holding his glove hand up. On top of all of that, he uses a glove that is extremely stiff and hard to close. For two reasons, one being to prevent against stingers in the palm, and secondly because he chooses to use his glove as a blocking tool when he holds it up. It stays wide open to provide more blocking surface area.
All these things together make him feel better about stopping the puck. Puck handling comes secondary to stopping the puck.
Or it's a skill in which he is mortal.
