In this wonderful clip we have a few issues. The original puck carrier is shoved from behind by the Dman. He goes into the desperation dive animation as he falls toward the blue line. He manages to dive away from the net and shoot the puck backwards with speed despite being completely horizontal to the ice in mid air and falling away from the net. The puck hits the goalie with enough force that there is a rebound to the left side. The other forward kicks the puck which phases through the goalies stick and through his legs, despite being squared to it. It then trickles in.
