Friday's night's 2-0 win over the Washington Capitals was big for the Islanders in a couple of ways.
The win vaulted the Islanders to first place in the Metropolitan Division - the first time they'd led the division after the midpoint in a season since March 10, 2015.
The win was Head Coach Barry Trotz's first against his former team in what was his first game back in Washington.
Most importantly, the win showed just how effective the Islanders' new defensive system can really be.
