The 22-year-old feels his body is fully recovered from the lower-body injury that kept him out for four games and because of that, he can handle the extra wear and tear placed on a centre.
"Part of it was just getting back into game shape," said Dubois, referencing the two-week quarantine, then the missed games due to injury.
"The second part was that with the injury being able to do all it takes in the centre position - battle in the corners, face-offs, stuff like that - I felt I was ready. I felt ready physically, I felt ready mentally. I'm ready to go."
Making such a shift in the line-up has a ripple effect on another line. Paul Stastny will move from centre to left wing, where he'll skate with Mark Scheifele and Blake Wheeler.
"Sometimes, when you're playing with another centreman and if I'm the first one back, it's easy because I can just play low and (Scheifele) can play wing," said Stastny. "Not much changes. It's the same thing, just (have) close support and just communicate out there because sometimes I'm first back, sometimes (Scheifele) is first back and sometimes (Wheeler) is first back and then you just rearrange from there."
Jets head coach Paul Maurice made the move halfway through the second period of Monday's game, as the Jets tried to find ways to generate offence.
They created a number of chances in the third period, outshooting Vancouver 15-4 as the Canucks worked to defend what was a 3-0 lead until Elias Pettersson's empty net goal with 3:34 to go in regulation.
