"It's exciting," McDavid said. "There are a lot of good young players that have a lot of speed and skill. I think we have the ability to surprise some teams."
Playing for Team North America gives some players the opportunity to skate with, instead of against, some of their peers. McDavid said he welcomes the chance to play with Matthews; McDavid (Canada) and Matthews (U.S.) were opponents at the 2015 IIHF World Junior Championship and the 2016 IIHF World Championship.
"I don't really know too much about him," McDavid said. "Obviously, he goes first overall and I heard all the hype. I have only played against him twice, and he's a very good player. I think he'll do well in the League."
McDavid said he isn't doing anything out of the ordinary to prepare for the tournament.
"I'm just training for the season," he said. "Obviously, the tournament is going to start a little bit earlier than most guys are used to, but I'm used to playing junior (where training camps start earlier than the NHL) … so to me it is basically a junior start. Nothing has really changed and I'm just preparing as if it's another year."
McDavid was third in Calder voting last season despite being limited to 45 games because of a broken left clavicle sustained Nov. 3. He had 16 goals and 48 points, and his 1.07 point-per-game average was third among players to play in at least 40 games, behind Patrick Kane of the Blackhawks (1.29) and Jamie Benn of the Dallas Stars (1.09).
Asked how he thought Team North America would do against older competition, McDavid said there's a "quiet confidence" among the group.
"That's really up in the air right now," he said. "We haven't been all together yet. But in talking with some of the guys, I think everyone has a quiet confidence. At the same time, I think we all understand we're the young bucks, the young guys, and nobody is really expecting too much from us. We'll see how it goes, but I think everyone is excited."
Ekblad said he's very much looking forward to Team North America's first game in pool play, against Team Finland on Sept. 18 (8 p.m. ET; ESPN2).
"I am very, very pumped to be a part of this tournament," he said. "I mean, it's the World Cup of Hockey, something that hasn't been around for a long time, and the players on [Team North America] think that we have a decent opportunity to make a splash in the tournament."
