The New York Islanders skated off with a wild and satisfyingly gritty win in their home finale. Their only regret is they didn't do enough in the first 80 games of the season to make this one meaningful. Michael Grabner scored his second go-ahead goal of the third period with just 46.8 seconds left, John Tavares helped set up two others to reach 50 assists this season, and the Islanders outlasted the Winnipeg Jets 5-4 on Thursday night.
