Last 30 minutes of that game was pure, dominating hockey by the Hawks. They're so deep all over the ice that they can rely on their defensemen (and even have them pinch) and goalie, allowing their forwards to have an aggressive forecheck. You saw it last night, where the Hawks destroyed Detroit in their own zone merely fighting for pucks and getting shots on net.
I expect the Wings to adjust and try to pass the puck out of the zone instead of carrying it out, but when the Hawks are rolling three/four lines deep like that, with the skill and aggressiveness on the forecheck and in their offensive zone, they're damn near impossible to stop. Beautiful thing to watch, let's hope they keep it up.
