He moved his stick 3 inches from the blue line when Smith shot the puck. Call it a deflection, but it didn't just happen to hit his stick like the puck happened to hit McNabb's skate on McDavid's goal. If Draisaitl had done nothing, the game would have went to OT.
Like I said, Skinner is maybe a backup goalie. He cost the team the game in the grand scheme of things. But that last goal is on Draisaitl. If Pickard had made that play, people would be blaming Draisaitl. God help us if it were Nurse who deflected it.
