Even before he was drafted by the Sabres, Cozens (first round, 2019) has had his sights set on the possibility of playing in the NHL as an 18-year-old.
"I believe I do have a shot at making the team," he told NHL.com last month. "Obviously not too many 18-year-olds make it, but I feel I have the size, I have the skating, I have the strength to be a guy who can step in at a young age.
"Obviously, I want to play when I'm ready and if they think I need another year to develop then I'll be happy with that, I'll be happy to go back to Lethbridge (Western Hockey League) and play there. But my goal now is to make the (NHL) roster."
How rare is it? In the past five years, only four players drafted outside the top five have gone on to play more than nine NHL games that season: Matthew Tkachuk (sixth overall; 76 GP), Jakob Chychrun (16th overall; 68 GP), Daniel Sprong (46th overall; 18 GP), and David Pastrnak (25th overall; 46 GP).
Far more often - even in the cases of stars like Mitch Marner and Mikko Rantanen - it takes another year of development before a player cracks the NHL full-time. Botterill has maintained that fact throughout the offseason while also leaving the door open on Cozens' chances.
"You always want your players to come in and have that belief [that they can make the team]," Botterill said at the draft. "We're certainly going to give him an opportunity. But the realistic factor, and I've been on the record saying it, is I think there's probably one or two, maybe three players who will step in and play in the National Hockey League this upcoming year.
"Probably the best thing for any player is to go back to junior and have that other year of development. But we'll see how the summer goes. As we've talked about before, Dylan is a very good athlete. He has great size and a great frame. But he does certainly need to get stronger."
