One player he has had the opportunity to impart some wisdom on is fellow Bruins defense prospect and 2016 draft pick Ryan Lindgren, who is at Team USA camp hoping to land a spot on his first World Juniors team.
"It's nice to have Lindy here," said McAvoy. "He's playing very well. It's great, the organization has not one but two guys in the running, and hopefully two guys on the final roster."
McAvoy is hoping to follow in the footsteps of a current Bruins blue liner. Boston rookie Brandon Carlo was a member of Team USA at the last two World Junior Championships and this year finds himself skating alongside Zdeno Chara on the Bruins' No. 1 defense pairing.
"I've seen the path that he's taken and kind of a lot like myself, playing in two World Juniors," said McAvoy. "Especially his second year around - my first year - he was a bigger part of the team, which I'm looking to be this year.
"Hopefully, if I can end up being in the same position he was this year, playing for the Bruins next season, that would be a pretty amazing couple of years, for sure."
But for now, McAvoy is focused on the present. The Boston University standout currently ranks second on the Terriers with 11 assists and is tied for fourth with 12 points.
"I think that I've tried to polish a lot of parts of my game and to take on more of a leadership role at BU, too," said McAvoy. "I think that I've done that and I think that, overall, things have been going very well.
"I'm looking to get into this tournament and take the momentum I have from school and play some great hockey. Hopefully, I come back with a gold medal and then worry about taking care of things in the second half at BU."
