5. Center Auston Matthews preparing for the big stage
Before Matthews plays for the Maple Leafs, the No. 1 pick in the 2016 draft will be watched closely in Toronto, especially by local media.
It will be fascinating to see how Matthews handles NHL competition, the pressure of Toronto's watchful eye, and playing on the wing or in a bottom-six role, or both.
Matthews performed well for the United States at the 2016 IIHF World Championship in May, leading the Americans with nine points in 10 games, but the World Cup will be the first real indication of how Matthews the NHL player, not prospect, handles the Toronto spotlight.
6. Ditto for forward Patrik Laine
Laine, the No. 2 pick by the Jets in the 2016 draft, is preparing to compete for Team Finland. While the focus will be on Matthews in Toronto, it will be interesting to see how Laine fares against the best competition in the world.
Laine won't be under the same spotlight or pressure as Matthews, but Finland, like North America, has medal aspirations and will be counting on the 18-year-old forward to come up with a big tournament. At the World Championship, Laine finished tied for fourth with 12 points, helping Finland win a silver medal. Finland lost to Canada 2-0 in the gold-medal game.
