Not necessarily.
If we were to go 3-1 or 4-0, especially if they are regulation wins, that would be huge for playoff seeding.
And we will, presumably, be getting Mrazek back at some point.
If we are still averaging ~4 goals a game AND have the inside track for the top seed when Petr gets back, we would have the flexibility to strategically rest some guys with minor nicks and scratches, and go into the playoffs as healthy/rested as possible.
