It's not as if Marcus Pettersson never had scored a goal before.
Heck, he'd gotten one as recently as, well ... uh, Oct. 23.
And this wasn't the first time he accumulated three points in a game.
That's something else he did on Oct. 23.
So no, none of this was new for Pettersson.
Well, except for one thing that he hadn't managed during his previous 293 NHL appearances.
And might not again, no matter how long he is in the league.
