Duchene, 22, chatted with Hockey Night in Canada Radio on SiriusXM on Thursday about Roy's heated confrontation with his Ducks counterpart Bruce Boudreau after a 6-1 rout over Anaheim.
It was classic Roy, who was known for his feistiness as a goaltender during his 18-year NHL career.
"We got to see some vintage Patrick Roy which was pretty exciting for everybody, including myself," Duchene told hosts Rob Pizzo and Cassie Campbell-Pascal.
"I felt like a six, seven-year-old again sitting around my TV screen in late spring. It was pretty great."
