Less than two minutes later, Brodie scored another odd one, banking it off the back of Greiss' right leg and in as Brodie was circling behind the net.
Fans barely had a chance to settle back into their seats before Ferland, just 42 seconds after Brodie's tally, won a battle for the puck along the boards and skated out a few strides before wiring it over Griess' glove hand.
The first-period pummelling ended with just 23.3 seconds left in the frame when, fittingly, No. 23 Monahan converted a one-timer off a pass from Johnny Gaudreau.
Jean-Francois Berube took over between the pipes to start the second period for the Isles.
Tavares finally got New York on the board with the lone goal of the middle frame, when a rebound from a Scott Mayfield shot dropped in front of him for an easy tap-in on the doorstep where he was parked in front of Elliott.
Versteeg restored the four-goal lead in the third when two Islanders crashed into each other in the Flames zone, springing a 3-on-1 rush for Calgary. Versteeg passed to Sam Bennett who tapped it back to Versteeg who snapped a one-timer home as he feel to his knees.
