TNT went on to highlight after whether the puck was offside as there were Canucks clearly in zone and one of them was getting off the ice into the door à la the Sharks call the San Jose fans didn't understand.
But the linesman caught that McDavid? knocked it into his own zone (I think by accident as he was being checked) and made a great call on the spot pointing to who, what, and why.
update: nm. saw the replay again and that was the Di Giuseppi goal that is playing second fiddle to JT's last minute winner which also deserves great moments.
You can see the great Linesman call at 4 seconds and details at the 47 second shows that it was Draisaitl who shot it in. TNT highlighted exactly the same.
Two great plays - one from DiG and one from Linesman
