But there is no real argument when reviewing the rules. 67.2 - You are allowed to catch the puck in the air, as long as you don't skate with it (or if standing still, hold on to the puck for a period of time). This doesn't happen in this play. As shown in the gif and the stills, he catches the puck a foot or two before the blue line and releases the puck while his skates are still on the blue line, fully in motion. Whole exchange takes less than half a second. Therefore, no penalty for Closing Hand on the Puck (That's just the name of the penalty, by the way, and also covers concealing the puck with your glove on the ice and picking the puck up off the ice). 67.1 - This then moves to Handling the Puck because the pucks squirts too far away from his stick from the act of releasing the puck while in motion. If he plays the puck at the red line, it's all good. If this all happened in the defensive zone (catching it, and playing it with his stick once it was on the ice), it's all good. However, the Bruins gained territorial advantage from the action, therefore it moves to rule 79.1 and is considered a Hand Pass (even though the pass is to himself). It's an infraction, blown dead, face off just outside the Bruins zone. It is not a penalty.
