You can argue about how bad the Pittsburgh loss really was, I guess, but coming off a poor showing against Buffalo, no Evgeni Malkin for the Penguins, and down 5-0 roughly halfway through — it was pretty damn bad.
To their credit, though, the team came out after the game acknowledged their issues and they responded with a resounding win. It was easily their most complete game of the season from top to bottom — they were tenacious getting the puck back, Frederik Andersen played well, and they won by four goals.
In the first period, there was a play where Auston Matthews made a second effort to win a battle below the goal line in the offensive zone to sustain possession.
