Umm... duh! Laine has a world class shot. He got that laser off on the PP while skating away from the net. He displayed good patience in waiting for the screen, and he rocketed a wrister at lightning speed. No goalie had time to react. He also positioned the shot in literally the perfect spot. If it was 1 cm to the outside it would've bounced off the pipe and out instead of inside the corner of the pipe. He could have shot it closer inwards because Ward wasn't set with his shoulders high. But even if he was, the shot still goes in.
To get that speed on the wrister, while moving, AND put it in the literal perfect position, shows just incredible skill. He'll be scoring from the top of the circles for many years. His other skills may not be world class yet, but Laine's shot is already there. That's why a guy like him goes #2. He doesn't have the hockey sense of Matthews or Kyle Connor for example, but they'll never have his shot IMO. Ideally you get him on a line with Connor (which he is) so Connor can get him in the right spots.
