All 31 NHL teams will have at least one player skating for one of the 10 countries; here are 10 drafted players to keep a close eye on during the tournament:
Carter Hart, G, Canada (Philadelphia Flyers):Hart, 19, will likely be Canada's starter for the second straight year, after helping them win the silver medal in 2017. A second-round pick (No. 48) in the 2016 draft, Hart has been the top goaltender in the Western Hockey League with Everett the past two seasons, and had a streak of four straight WHL goalie of the week awards ended this season because he was at Canada's final WJC evaluation camp. In 17 games this season he leads the WHL in goals-against average (1.32), save percentage (.961) and shutouts (five).
Miro Heiskanen, D, Finland (Dallas Stars):The No. 3 pick of the 2017 draft, Heiskanen, 18, recovered from a concussion sustained in September and has 14 points (nine goals, five assists) in 20 games with HIFK in Liiga in Finland. He could be one of five first-round NHL draft picks on Finland's defense, along with Olli Juolevi (Vancouver Canucks, No. 5, 2016), Juuso Valimaki (Calgary Flames, No. 16, 2017), Urho Vaakanainen (Boston Bruins, No. 18, 2017) and Henri Jokiharju (Chicago Blackhawks, No. 29, 2017).
