These players have jobs. They have areas of the game they are responsible for and where there is little or no option. You are behind by a goal in the 3rd period and you need to win the game and you are going to bench Carlson? In favor of who? Who brings that offensive game in his place? If Kuzy is having a rough game, you give his ice to Dowd?
Carlson is definitely tougher because Orlov is the only other offensive Dman. But maybe when Carlson looks like he doesn’t give a damn defensively like he did last night, you don’t play him as much 5v5 when the game was tied or the Caps were leading. And maybe you let Orlov play the 6v5 at the end. Maybe not, but with how poor his effort was last night I would think you cut his minutes somehow, no?
As for Kuzy that’s pretty easy. Give his ice time to Eller. Eller’s line should be playing more in general anyways with how well they have been playing as of late. They’ve been the only consistent line.
There’s been very minimal changes to lines, competition for ice time, etc. I don’t think rewarding players with more ice time for playing well is a bad idea, neither is punishing players that are playing lackadaisical.
