"It's time to start looking like Team USA." That was the approach after a shock opening Olympics loss, Damian Lillard said, and the Games favourites delivered on Wednesday.

France had upset the United States in their first game, following up a 2019 FIBA Basketball World Cup quarter-final triumph against the same opponents.

It was a defeat that will ensure doubts remain about Team USA's title aspirations for some time, but they at least got back to winning ways against modest opponents in Iran.

Lillard led the way in Wednesday's stand-out game, scoring 21 points in a dominant 120-66 success.

"I think after our loss to France we had two days between games and everybody just wanted to get back out there and get right," the Portland Trail Blazers guard said. "After that loss, we came together."

Lillard added of the Iran game: "I think we came out with a lot more urgency. Our energy was higher, we played at a faster pace. We were more aggressive, and we played like ourselves.

"We didn't come out here and think that it was just going to happen; we made it happen, and that's the way that we've got to play if we want to be successful in these Olympics."

'WE DON'T NEED HEROES'

Lillard's game-high tally – consisting entirely of seven three-pointers – was still significantly down on the 28.8 he averaged in the 2020-21 NBA regular season.

But that is exactly what coach Gregg Popovich wants from his team, knowing Devin Booker (16 points on Wednesday, 25.6 in the NBA), Jayson Tatum (14, 26.4), Zach LaVine (13, 27.4), Kevin Durant (10, 26.9) and Khris Middleton (10, 20.4) cannot all be the main men.

"Each of these guys scores 20 or 25 or 30 for their teams, and their teams depend on that every night," Popovich said. "We can't play like that, and so we don't.

"They appreciate each other and they know what their team-mates can do. They understand that good basketball is sharing the basketball.

"Everybody's, in a sense, kind of a role player now. We don't need heroes."

FRANCE TAKE TOP SPOT

Les Bleus built on their victory over Team USA and will now top Pool A ahead of the American side thanks to a 97-77 defeat of the Czech Republic.

France trailed 28-22 through the first quarter but turned the game around with a dominant second, settled 29-12 in their favour.

As against the United States, Evan Fournier topped the scoring charts, weighing in with 21 points on 62 per cent shooting.

BOOMERS BIGS WIN BATTLE

Australia also have two wins from two after edging Italy 86-83 on Wednesday, led by the frontcourt contributions of Jock Landale and Aron Baynes.

Landale led the Boomers with 18 points, but the pair crucially also finished with seven rebounds and a block apiece. Between them, they accounted for nine of the team's 16 vital offensive rebounds – Nick Kay added another four from the bench.

"Our bigs were huge today," said Utah Jazz wing Joe Ingles. "The rebounds, tip-outs – they got us a ton of extra possessions."

Elsewhere in Pool B, Nigeria's pre-tournament optimism might have given way after a second straight defeat that gives them a mountain to climb.

D'Tigers beat Team USA and Argentina in exhibitions but lost to Australia and then, on Wednesday, Germany – a 99-92 reverse despite 33 points from Jordan Nwora, fresh from playing a fringe role in the Milwaukee Bucks' run to the NBA title, including one minute and three points in the Finals.
