McAvoy was somewhat rushed to the NHL; the Bruins were missing four defensemen because of injuries during the playoffs. General manager Don Sweeney has spent the summer trying to strike a balance between having depth and competition, and providing an opportunity for younger players.
The Bruins lost defenseman Colin Miller to the Vegas Golden Knights in the NHL Expansion Draft and signed veteran defenseman Paul Postma as an unrestricted free agent from the Winnipeg Jets on July 1. Boston has been less active since then, partly because it's negotiating contracts with restricted free agent forwards David Pastrnak and Ryan Spooner and partly because it wants prospects into the lineup.
"I don't think anybody really used the word 'giving' spots to anyone around here. I think everybody's going to earn their opportunity, their ice time," Sweeney said. "There are potential opportunities that exist, and I'd like our players internally to step forward and grab them."
That talk about giving younger players a strong chance to make an impact in the NHL pleased McAvoy.
"I think that Donnie always is going to put the team in the best position to have success. The way he talks about being committed to the younger guys, that's something that's really special to hear," McAvoy said. "You get excited if you're a young guy like me hearing something like that and knowing what he's committed. You definitely want to put your best foot forward and earn your spot out of camp. Going into it knowing that you're going to get every opportunity is awesome."
