Though they have done that, there are four other teenagers chosen in the first round who each made his team's 23-man roster: forward Owen Tippett (Florida Panthers), center Martin Necas (Carolina Hurricanes), center Filip Chytil (New York Rangers) and forward Kailer Yamamoto (Edmonton Oilers).
It's a bit of a surprise, particularly because there isn't expected to be a generational talent the likes of Oilers center Connor McDavid (No. 1, 2015), Buffalo Sabres center Jack Eichel (No. 2, 2015), Toronto Maple Leafs center Auston Matthews (No. 1, 2016) or Winnipeg Jets forward Patrik Laine (No. 2, 2016) among the group.
"While there wasn't that generational player, that doesn't mean you won't find players capable of playing in the NHL," said David Gregory of NHL Central Scouting. "I think the fact there are [so many] players still with their NHL team just says that maybe the draft might have been a little deeper than expected, and players are becoming more NHL-ready at a young age."
The NHL's Collective Bargaining Agreement allows for nine games at the start of the regular season when a player on his entry-level contract can be evaluated. The player can be returned to his junior team without his contract kicking in at any point before the player dresses for his 10th game. If the player skates in more than nine games, he still can be returned to his junior team, but the first year of his contract goes into effect and the player could reach free agency at an accelerated pace.
