Cassidy acknowledged that the coaching staff will "look at" potential changes to the third line for Game 5. Boston's bench boss said the trio of Nick Ritchie, Charlie Coyle, and Jake DeBrusk "didn't generate anything, to be honest with you" in Game 4 and pointed out that they were on the ice for the Islanders winning goal in the third period.
"They've had better games," said Cassidy. "Obviously, a breakdown on the last goal. Our winger went down, should have had more patience. Allowed them to get to the middle of the ice and it kind of snowballed from there where guys were late because we didn't do our job first. That part of it hurt us."
Cassidy said that Trent Frederic - while noting that the young forward has not played since the regular-season finale - and Karson Kuhlman would be possibilities to enter the lineup.
"We'll see what we can do on the third line," said Cassidy. "Kuhlman's played a little bit, Freddy hasn't played in a long time. Those are the guys that have been with us the longest. You've got left wingers having to go to their right side, unless it's Kuhlman. We'll consider it and we'll go from there."
While the third line could change, Cassidy said he will not be making any tweaks to his fourth line of Sean Kuraly, Curtis Lazar, and Chris Wagner, calling their performance in Game 4 their strongest of the series.
"I thought [Saturday] night was our best game from our fourth line in terms of playing below the goal line, getting pucks deep, being physical," said Cassidy. "Lazar draws a penalty by being physical, a cross check to the head there. Good for him for trying to finish his checks. I thought Sean was trying to do more of that. Wags had a good chance in the first period on a wraparound later in the slot, it was just off-net.
"I thought they did a better job than they had been in terms of offense and how they can best do it, which is on the forecheck, turnovers, putting pressure on the D. That part I liked. And their penalty kill was good."
