I'm not sure if I missed it being mentioned in the thread, but one thing that really impressed me in this game was that McDavid gave up his own opportunity for his own first hat trick in order to get Eberle his hat trick.
It was a VERY unselfish play - it's not like he was desperately trying to make the highest percentage play to ice a game where the other team was still threatening to win. He had virtually no risk to the game in trying to get his own personal accomplishment, but still gave that up to get another player his own accomplishment.
I know I'm preaching to the choir here, but a player who can be as spectacularly good as McDavid, AND that selfless is a very special player indeed.
I think creepy Mess had it right:
