The Islanders have been idle since Monday. The Islanders will use that energy for defense and checking because that is their makeup. 
It's only been three games, but the Islanders have shown their consistency. They've scored five goals in three games and given up five goals in three games. There hasn't been more than five goals total scored during each of their first three games with all three games going Under. 
Both teams have hot goalies. Semyon Varlamov has shutouts in his two starts, while the Devils' Mackenzie Blackwood has a 1.90 goals against average with 109 stops on 115 shots. New Jersey has allowed just seven goals in its three games.
