These are known as the "get right games."
The kind of game where everything goes your way, you completely dominate an opponent and almost everybody on the roster has a chance to fill up the score sheet and get their stat lines back on track. They are not only great on an individual level, they can also be a springboard for teams as a whole.
Hopefully for the Pittsburgh Penguins sake their 7-0 win over the New York Islanders can be exactly that. They simply could not have asked for a better start coming out of the holiday break.
