Based on the combination of images, it can be safely assumed that Thompson’s stick is along the same vertical plane as his right skate. As this is the point of his body closest to the net, this provides a conservative estimation. By the laws of physics (yes, all of them), the net’s profile will shrink in all directions as the distance from the camera increases. This shrinkage was ignored to keep with a conservative estimation (mainly because we have final exams coming up), and it was assumed that the 48″ net height was consistent across the entire y-axis of the rink. By projecting the net profile to the plane where Thompson contacts the puck, we can determine whether there was a high-stick on the play by looking at his stick relative to the projected net profile. If his stick is inside or level with the profile, then there was no high-stick on the play, confirming the NHL’s decision.
