I answered my question:
Last time we scored 8 goals:
8-5 Win vs Boston on November 8, 2018.
Prior to that it was an 8-2 win vs the Avalanche in November 2009.
Poor Marky. He'd be one of the three stars most nights with this performance, but he's got so much goal support, he might not make it at all, haha.
I'm sure he's okay with it.
If Hughes and Tanev spend the entire year together, I'm predicting a career year for Tanev provided he's reasonably healthy (a relative term for Tanev).
