IRVINE, Calif. — In one country, the comment was a throwaway line amid an instant reaction to the World Cup draw. For the other nation, it became a rallying cry.Layup.That’s what CBS Golazo Network analyst Mike Grella called the United States drawing Australia from Pot 2 in a live show reacting to the draw as it took place on Dec. 5. It was his initial, raw instinct. Grella has repeatedly said since that he didn’t mean any deep disrespect by it, but the clip ultimately went viral on two continents in two hemispheres — to the point that it’s been Australia’s drumbeat for motivation for six months.That talk only intensifies this week ahead of the long-awaited World Cup showdown between the U.S. and the Aussies on Friday in Seattle (3 p.m. ET). The difference now is it is a top-of-the-group clash with potentially decisive stakes after the U.S. thrashed Paraguay, 4-1, and Australia blanked Turkey, 2-0.Underpinning it all, and a big part of why Grella’s words touched a raw nerve, is a spiky rivalry between the two sporting nations that carries some angst and underdog annoyance, and has the Australian public and national team genuinely irked.It is one that crosses over sports and has spanned some generations. It is certainly more keenly noticed on the Australian side, and, rather unexpectedly, has a big part of its foundation in the sport of swimming.Gary Hall Jr. shakes the hands of Australia’s 4×100 freestyle team after a famous gold medal showdown at the 2000 Sydney Olympics (Timothy A. Clary / AFP / Getty Images)Gary Hall Jr. knows what it’s like to be in the crosshairs of Australia’s collective sporting ire. A former five-time Olympic swimming gold medalist, Hall fired up Australia’s competitive flames ahead of the 2000 Olympic Games in Sydney, perhaps even more unwittingly than Grella.Writing a series of athlete diaries for a U.S. publication, Hall penned a column that was intended as being praiseworthy of Australia’s swimming culture, and critical of the American version. His article also included a line indicating that while he had great respect for Australian swimming and the Aussies’ 4×100 freestyle relay team, his “biased opinion says that we will smash them like guitars” before adding that the logical part of his brain expected a fiercely contested battle in the Sydney pool.Only the spicier part of the quote made it across the water to Down Under, and when it did, it created a national frenzy in a nation excitedly gearing up for what would turn out to be a spectacular Olympics.“The plane landed in Sydney and before we got off I guess they brought a bunch of newspapers up to the plane to restock it before the next flight,” Hall told The Athletic on Monday. “I saw a U.S. team official pushing against the human traffic to make his way back to me. He held up a newspaper that had my face on it and said ‘what the f*** did you do?'”Hall was soon thrust into an extraordinary whirlwind. He was voted the most hated man in Australia, confronted about his comments at every media session, booed by the home crowd and, when Australia’s Ian Thorpe touched him out on the relay’s final leg, had to watch as the Australian team unfurled a now-infamous air guitar celebration.Hall was shaken by the experience and even with all the years in between, was only half-joking when he said a call from The Athletic asking him to relive it gave him “a bit of a twitchy eye, so thanks for that.” He claims that in the six years that followed he was unable to land any major sponsorships, unfairly portrayed as the arrogant American who upset an entire nation. The irony is, he had several friends on the Australian team, and held a great respect for the sports-mad country.“There are plenty of similarities between the countries in a sporting sense,” said Hall, who lost his home and possessions — including his Olympic medals — to the Southern California wildfires in 2025. “The ‘hold my beer’, true grit kind of stuff, that’s the spirit that settled the West. That sort of frontier mentality and competitiveness, that is a common bond between us.”There’s a major difference between Hall and Grella, which is that one was an active athlete speaking in the heat of battle and the other is an ex-player, who’s now a pundit. Nevertheless, while Grella’s one-word analysis has remained a constant talking point ever since it was uttered, there’s something the players inside both locker rooms can agree on: they’re done discussing and hearing about it.
