Boston Bruins - Urho Vaakanainen, D (Round 1, 2017)
A concussion limited Vaakanainen to 32 games - two with Boston and 30 with AHL Providence - during his first North American season, but the 20-year-old defenseman impressed on the world stage. He skated a team-high 25:08 in Finland's World Junior victory over Team USA, where he won gold alongside Sabres prospects Jokiharju, Oskari Laaksonen, and Ukko-Pekka Luukkonen.

New Jersey Devils - Jack Hughes, F (Round 1, 2019)
Hughes set program records for assists (154) and points (228) during his two seasons with the US National Team Development Program. Now, he's looking to become the first player to go straight from the NTDP (which also produced Jack Eichel and Auston Matthews) to the NHL.
The 18-year-old centerman already got a taste of NHL competition at the World Championship in May, where he was teammates with Eichel for the United States.
