If the player remains out for the playoffs it's a bad break, but if you're, say, Boston or Florida, You'd almost rather have someone like Marchand out until playoffs when he's rested and with a team playing with an additional 7 mill (or whatever he makes). So, basically being healthy, especially if you're already a good team that can succumb the loss of a top player, you kind of get the shaft whereas teams that have the luxury of being able to stash someone for financial gains get lucky. The rich get richer.
As I've said many times here, health should not be a detriment.
