Moore knows he's auditioning for a spot.
"That's been my M.O. every single training camp, to show up and earn it and put my best foot forward," said Moore, who added that he has played at times on his off side. "I don't feel like anything is owed to me. That's not the way this League works. There's an abundance of very talented defensemen here. So just like anyone else, it's an opportunity for me to show what I can do."
But there is one fewer defenseman.
"I think the uncomfortable part was [going to be] telling two players they couldn't play every night. It's always good to have depth, so there's good and bad," Cassidy said.
Depth was a particular concern for the Bruins for the past two Stanley Cup Playoffs. In 2017, Carlo, Krug, McQuaid and Colin Miller were out with injuries during Boston's six-game defeat to the Ottawa Senators in the Eastern Conference First Round. In 2018, the Bruins lost Carlo and Krug and were defeated by the Tampa Bay Lightning in five games in the second round. So the Bruins front office keenly understands the need for quality reinforcements.
Still, the decision to trade McQuaid made sense. The log jam has eased a bit. So have the minds of some of the players.
"I'd say a little bit," Carlo said. "That was a big question for a lot of people coming into camp with the eight defensemen. Overall, I feel like you never know on any given night, any seven of those guys can play. So it'll be interesting still with that. But I think we have a strong core going forward."
McAvoy went even a step further.
"I think our D corps is going to be special," he said. "I really do."
