Despite the disparity in the standings, and being severely undermanned, the Islanders paid the Blue Jackets the proper pregame respect, born of three one-goal wins earlier this season.
Columbus showed why in the second period, rattling off four goals to turn a 1-0 Islanders lead into a 4-2 Blue Jackets advantage by the break.
Johnny Gaudreau's power-play goal at 4:58 tied the score 1-1, coming just over a minute after a Kirill Marchenko goal was successfully challenged and overturned by the Isles due to goalie interference. The challenge was Lane Lambert's second successful challenge this season.
The tie game didn't last long, as Nelson reestablished the Islanders, one-timing a quick Kyle Palmieri feed after the Islanders created a turnover during a Blue Jackets breakout. Nelson's goal was his 31st of the season and it game 32 seconds after Gaudreau's equalizer.
Columbus didn't go quietly, as Liam Foudy tied the score 2-2 at 8:59, converting a Jack Roslovic feed after an Islanders turnover deep in the d-zone. It was a fairly even game at that point, but the Blue Jackets broke it open with a pair of goals 40 seconds apart to end the period.
"Things were just sloppy," Palmieri said. "We eeren't moving our feet. Weren't unable to really generate any speed to a neutral zone or coming out of our zone and it ends up being slow and kind of on our heels."
Kent Johnson put Ilya Sorokin on the wrong end of a highlight reel, which is rare of the Isles netminder, when he scored a Michigan at the 17:06 mark. The lacrosse style goal was Johnson's third, previously scoring them in the BCHL and the World Juniors.
Eric Robinson made it 4-2, 40 seconds later, as Emil Bemstrom's centering feed caromed off Robinson and in. Friday marked the fourth time the Islanders had given up four goals in a period, most recently allowing four goals in the middle frame of a 5-2 loss to the LA Kings on March 14.
