"Some people might always link us together," Dubois said. "For me, the way I went about it this year is you can't compare yourself to anybody. You're your own player. It's not just about stats. It's the small details in your game."
Dubois admitted to being taken aback when he heard Columbus was selecting him with the third pick. He also heard rumblings he could be taken as low as sixth.
"Everyone was talking about the Finns going two, three," Dubois said referring to Patrik Laine, who went to the Winnipeg Jets at No. 2 after the Toronto Maple Leafs made American Auston Matthews the No. 1 pick. "In the long run I think I can be one of those guys in the top three.
"I was a little surprised at first but the way the season went on I got better and better. I worked really hard. I got stronger and faster. My ceiling is really, really high."
Dubois finished third in league scoring with 42 goals and 99 points and became the first QMJHL player since Sidney Crosby (Rimouski, 2005) to place first among North American skaters in the NHL Central Scouting's final rankings.
Sonny Milano, the Blue Jackets' top pick at No. 16 in 2014, said Dubois can't worry about being linked to Puljujarvi.
"I don't know if the comparison with Puljujarvi will be there his whole career," he said. "I'm sure it will fade away. He can't worry about that stuff, honestly.
"Being a high draft pick they put a lot of pressure on you. They expect you to be a player one day. First or seventh round, no matter how good you are, you have to put pressure on yourself to make the team one day."
Dubois said one reason he was not in the top three in many draft boards is his game picked up late in the season after moving to center.
"Everybody has their opinions," he said. "I was more of a late bloomer. Nobody knew a lot about me at the beginning of the year. As I got better throughout the year, people started paying attention.
"I think the fact I played center showed a different part of my game nobody knew about. Also, I gained 40 pounds the last three years. I grew three inches. I'm getting stronger and faster."
The physical changes altered his game.
