Does he have trouble elevating the puck? I hope he's doing drills picking the puck off the boards, cutting to the middle & shooting. He needs that wired in his brain.
No, the play in question was a very hard cross ice pass, and it is VERY hard to pick top corner on those with the snap shot as the slightest imperfection in technique will send the puck soaring over the net. It was a damn good save, and honestly it almost snuck between Fleury's glove and pad.
The more important thing was he shot it near side, which was made the save so difficult, instead of like many middling and non offensive players who'd shoot it center mass and end up hitting the goalie in the chest.
Kakko passed up a shot in the third when they were tied and Lafreniere was down low with him in a 2-on-2 when he did, so I got the sense KK wasn't being timid, but was trying to help break Laf's drought.
