At 4:07 of the second period in the Penguins/Bruins game, video review supported the referee's call on the ice that the puck deflected off Tom Kuhnackl's skate and into the net in a legal fashion. According to Rule 49.2 "A puck that deflects into the net off an attacking player's skate who does not use a distinct kicking motion is a legitimate goal." Good goal Pittsburgh.
