You may not need the big, hulking guy anymore, especially if he isn't a great skater, ... If you can't lay a stick on the guy, they may not be as effective.
This is a good thing for us. We use a shorter bench, there's no secret to that. Our top-end players play a lot of minutes. This has been a great rest for those guys. It also gives us, as a coaching staff, a chance to see some games we wouldn't normally have a chance to see.
