At this point you have to stick with it until something changes. Eventually the Rangers will lose a game. At that point you can justify a lineup change.
You can't change a lineup that's won five in a row in the playoffs because Carolina may score on a power play that Rempe might get just based on his reputation.
You can't change a lineup that's won five in a row because eventually playing one guy 6-7 minutes a night might catch up them in terms of who's taking on more minutes because of that.
When it happens you make the change. You certainly don't make it for a home game. And you certainly you don't make it because you're worried something that hasn't happened, might eventually happen.
