Ottawa center Marco Rossi, No. 6 in NHL Central Scouting's final ranking of North American skaters, said that he likes what he sees in Quinn.
"[Quinn] competes really hard, is really fast, a good skater and has a really good shot ... and he loves to work hard," said Rossi, who was the top scorer in the CHL with 120 points (39 goals, 81 assists) in 53 games.
Quinn led Ottawa with 240 shots on goal and ranked third with seven game-winning goals. He scored 32 points (12 goals, 20 assists) and had 92 shots on goal in 61 games as a rookie in 2018-19.
"Training with Tony was good for me," Quinn said. "We had a good group there and it really helped my skating, my explosiveness and just my overall conditioning. I've noticed a big difference this year on the ice."
The 18-year-old, who missed the cutoff for the 2019 NHL Draft by four days, considers it an advantage to be one of the older prospects entering the 2020 draft.
"It's an advantage in the sense that I got to play another year in the league before the draft," he said. "Obviously it's another year to figure the league out and I think I figured things out a lot between last year and this year, so just an advantage in that it was just more time to kind of understand the league and develop your game."
Director of NHL Central Scouting Dan Marr said Quinn really hit his stride this season.
"Jack is smart and plays a hard-driving game with good speed and instincts to execute plays and produce offense," Marr said. "He's clever and poised with the puck, competes responsibly to play a two-way game. There's a lot of upside potential."
Quinn played much of the season on a line with Mitchell Hoelscher, who was selected by the New Jersey Devils in the sixth round (No. 172) of the 2019 draft.
