McDavid and Matthews didn't really know each other until later on in their junior careers. Matthews says he may have played against McDavid at a very young age at "some tournament in Canada", but he doesn't remember. McDavid says the first time he really understood who Matthews was, and the calibre of talent he possessed, wasn't until his second World Junior appearance.
"I never really saw him in my (younger) hockey I don't think," said McDavid. "I heard of him, going into World Juniors my second time around in my draft year. That would have been the first time I actually saw him play."
"I heard about him when he got drafted into the OHL with his exceptional status," said Matthews. "That was the first time I'd heard of him."
Now the two are very familiar with one another. They were teammates, and occasional linemates, on Team North America at the 2016 World Cup of Hockey.
"He's just a really special player," said Matthews.
"He's such a good player," said McDavid. "He's quick and he's got a lot of skill and a good shot. He's pretty hard to shut down."
As Gretzky knows from his playing days, when the expectations go up so does the internal competitive fire.
"It fires you up… It's a team game but individually, you have pride too and that's what makes superstars Hall of Famers," said Gretzky. "You have that pride as a player and an athlete. Although the concern is about the team, you get fired up."
"From my perspective, the best athletes want to be in those situations, whether it's Larry Bird and Magic Johnson or John McEnroe at Wimbledon or Mark Messier in a Game 7," Gretzky added. "The best athletes accept that responsibility and they don't look at it as pressure. They look at it as fun. We used to say in Game 7s, 'where else would you rather be?' It's what we dreamed about as kids. If you accept that and understand the responsibility, it makes the game that much more fun."
But now, when they face each other, the two will be in direct competition. Their respective teams both boast some quick, dynamic, young talent, which could also link the squads in comparisons moving forward.
"Obviously, everyone is excited about it," Gretzky said of the two players, and two teams. "You get two premiere young players in hockey that are obviously the future of both organizations. You throw that in with a bunch of other kids who are playing really well, it's exciting for Toronto and Edmonton. It's not just Auston, it's not just Connor. There's some good young players on both teams. Expectations go up with that."
The Oilers and Maple Leafs likely don't face each other often enough for a true rivalry to develop, with only two matchups per season. But as these two young stars grow and pull the League along with them, the two teams are likely to be linked - just like the two individuals who battle tonight for the first time in the NHL.
