I agreed with "can't panic, stick to your game" for games 4 and 5, and the result was the exact same as game 3. When you're facing elimination on the road, where you've played terribly, having lost 3 games in a row, what better time is their to shake things up? This could very well be the last game of the season.
Considering no one has really generated much at all offensively, I'd go with something like this. Veteran presence on all lines. They don't have last change, so don't worry about match ups and roll all 4. Could lead to a fresher team and more offense, as the current 4th line barely gets used.
