Cassidy confirmed that Mike Reilly and Jakub Zboril will team up as Boston's third dense pairing with Zboril switching to the right side in place of Connor Clifton, who will be a healthy scratch against the Flyers as Boston's bench boss looks for a bit more consistency in the blue liner's game.
"We went with Cliffy, he obviously had earned the trust of the staff, has been around, it fit better [as a right shot on the right side]," said Cassidy. "At the end of the day, you've got to perform every night consistently. I think Cliffy is still battling through some of that, even in-game. Example the other night [against Montreal], has some big, physical moments, breaks up a 2-on-1, but also goes diving down [in the offensive zone] in a situation that now we're chasing the game.
"At the end of the day, Zboril goes in, does his job, moves the puck a little bit, a little more dynamic offensively, yet still solid defensively, so he shouldn't get frozen out either. There's that to balance."
Reilly, meanwhile, will re-enter the lineup after sitting out last weekend's back-to-back as a healthy scratch on the heels of some up-and-down play of his own.
"Mike was a little bit more of a message, I'll be the first one to tell you that," said Cassidy. "I would assume he hopefully gets it and gets to his level and stays in the lineup every night. That was the plan. The other guys are less father along in their careers so it's a little bit more of a battle for the other two."
