Gamble pays off as Dupont seals France's Paris Olympic sevens dream
The France and Toulouse 15s captain again received a rapturous welcome from a raucous Stade de France for the final against Fiji, which the hosts won 28-7 in front of President Emmanuel Macron.
"A huge reward for us, for rugby, for all the country," Dupont said.
"We really felt that we were representing not only rugby but the whole of French sport. We are really proud to start the Olympics like that."
Dupont added: "It's such a great honour to win this title and I have such great emotions.
"It is such a great thing to achieve with these boys. It's really top of the list.
"I just want to share this with my teammates. We worked so hard for so long to do this. This is just the cherry on the cake."
Dupont has established himself as one of world rugby's best players and the scrum-half cuts an iconic figure in France.
The 27-year-old took the gamble of missing the Six Nations to make the French Olympic team, a move that led to some criticism.
But the combative half-back put that to one side, going on to help France to two wins on the World Rugby Sevens Series, including victory in the Madrid finals.
In between, he skippered Toulouse to Top 14 and Champions Cup glory in the 15-a-side code.
After starting the opening two pool matches at the Games, Dupont was named on the bench for the final pool game and the knock-out phases as coach Jerome Daret plumped for Stephen Parez-Edo Martin in the playmaking role.
"It's always more difficult to be on the bench... because we cannot do anything. It's more stressful than playing," Dupont admitted.
"But this is a part of being in a squad and the most important thing is the victory."
Daret dubbed Dupont an "exceptional player whose entry into the game piles a lot of pressure on opponents".
Immediate impact
Wearing the number 11 shirt, Dupont came on for the second half and made an immediate impact in the final against reigning two-time champions Fiji.
The ball was knocked back to him and immediately he was off, rounding Fiji captain Jerry Tuwai and shooting up the left wing.
He popped a try-scoring ball back inside for Aaron Grandidier Nkanang.
That pulled France clear and with Fiji under pressure, Dupont crossed for a brace of well-taken tries in a script that could not have been written any better.
World Rugby CEO Alan Gilpin showered praise on local hero Dupont, telling AFP that what Dupont had achieved was "mind-boggling".
Dupont's presence ensured a 69,000-capacity crowd at the Stade de France, with World Rugby expecting more than half a million fans to attend the six days of sevens action.
The last time Dupont played at the stadium north of Paris was in a 29-28 defeat for France against South Africa in the Rugby World Cup quarter-final in October.
Dupont's absence from the Six Nations to focus on making the Olympic team did not sit well with many traditionalists.
But his appearance at the Paris Games was a huge coup not only for French rugby as a whole, but also the organisers.
"I think it speaks volumes for his passion for representing his country at Olympic Games," Gilpin said of the Frenchman's decision to skip the Six Nations to focus on sevens, often seen as rugby union's poor cousin.
"But I think it also speaks volumes for him understanding that the Olympic Games is an unbelievable platform for a star player.
"Rugby sevens is great for the Games and the Games is great for rugby sevens and that's absolutely what we want."
Gilpin added: "Let's be clear, what Dupont has done is almost impossible."
"It's mind-boggling," he added.
As for Dupont, he said he was looking forward to taking a holiday, but would not be resting on his laurels.
"Afterwards we start a new season. I'm still young and I have a lot of work to do."
