The inability to sustain any offensive zone time led to Islanders coach Jack Capuano shuffling his lines, including breaking up the second line of Josh Bailey, Brock Nelson and Nikolay Kulemin, who haven't been able to support top center John Tavares, the scorer of New York's only goal in Game 4.
"You need contributions," Richards said. "As a coach, you're just trying to spark something or someone when you start juggling and mixing lines; you're looking for any type of spark. And who knows? Maybe there was an injury or there was an equipment malfunction where somebody was missing a shift here or there, or maybe it was just Jack saying, 'You know, I'm going to change things up and try to get a spark.'"
The series shifts back to BB&T Center for Game 5 on Friday (8 p.m. ET; CNBC, SN, TVA Sports 2, SUN, MSG+). Richards thinks it might be good for the Islanders to get back on the road, where they earned a split in the first two games and were solid in Game 2 despite a 3-1 loss.
"There's more of a focus, and sometimes when you play at home you get wrapped up in your crowd and what's going on with your crowd," Richards said. "There's certain momentum and energy you can get from your crowd, but it can only be a negative if the visiting team is coming out and doing its job. Instead of fans cheering and urging you on, they start booing you, and then that adds to a little bit more pressure.
"I think sometimes playing in the big games, I've seen Game 7s where I know a team's going home, they've got home ice, but I still think sometimes that's a little bit harder. Sometimes Game 7s are better to be played on the road."
