Deployed as a loose man in defence for the majority of the contest against the Demons, Oxley gathers a team-high 30 disposals and 14 marks in a best-afield performance for Collingwood.
The 22-year-old also had a round-high eight intercept marks in the Magpies' 25-point win.
Oxley credits former Magpie skipper Nick Maxwell for his development as a defender at the club.
"I did a lot of work with Nick Maxwell the first two years I was here and he was telling me how important it was to take those marks in front of the opposition team's forwards," Oxley said.
"I pride myself on my aerial power and I've been working on it a fair bit at training jumping into the bag and coming off my man."
