In-Game 6 of the contentious L.A. Kings and Edmonton Oiler's series, Evander Kane threw up 7 fingers as part of his celly. It appeared like in the group celebration McDavid was frustrated with Kane's celebration.
Kane has experienced an undeserved redemption arc, thanks to Ken Holland and the Oilers are benefitting. The Oilers have really copied and pasted mediocre goaltending, with a high offensive output to stay alive, in spite of the Kings' fight to stay in the series.
