Bettman says he’s okay if you want to bring back the rule against forward passes, he doesn’t mind if you want to revert to old-school icing, he just demends you keep it to one rule change; you know, evolution is better than revolution…
What rule are you changing, tweaking, binning or creating.
It’s also a big advantage to defenders in general, as icing the puck would now allow lines to change, instead of one team getting stuck on the ice for long periods in their own zone.
