To say that USA Basketball had a rocky training camp heading into the 2021 Olympic Games in Tokyo would be an understatement. The senior men’s national team lost its first two exhibition games in Las Vegas, had three players enter the health and safety COVID protocols, and two players dropped out.

Even head coach Gregg Popovich got off on the wrong foot with the media as he was involved in a testy exchange with a reporter after Team USA fell to Australia 91-83.

Popovich and his staff, which includes Golden State Warriors coach Steve Kerr and former Atlanta Hawks coach Lloyd Pierce, have a gigantic task ahead of them. The 2021 squad has only been together for two weeks and have played just four exhibition games, going 2-2. It has already undergone multiple roster changes after Washington Wizards guard Bradley Beal and Cleveland Cavaliers forward Kevin Love both left camp.

Beal’s exit was COVID-related, while Love was due to an injury. San Antonio Spurs forward Keldon Johnson and Denver Nuggets center JaVale McGee were added to the 12-man roster. In addition to those moves, the team will need to absorb Phoenix Suns guard Devin Booker and Milwaukee Bucks teammates Jrue Holiday and Khris Middleton as all three just finished playing in the NBA Finals. So, we won’t be able to see all 12 players together on the court until the team’s opening game on July 25 against France.

Then there’s the large shadow of Mike Krzyzewski. The legendary college basketball coach had a remarkable 10-year run as head coach of USA Basketball, winning three Olympic gold medals and two FIBA World Cup titles and finishing with an astounding 60-1 record. That’s quite a tough act to follow for Popovich, who has already lost five games since taking over USAB’s senior men’s squad in 2017.

Under Popovich, Team USA hasn’t won a significant international tournament and had a disappointing outing in the 2019 FIBA World Cup, failing to medal and finishing seventh.

Coach Pop has two holdovers from Krzyzewski’s 2016 gold medal team in Rio: Kevin Durant (Brooklyn Nets) and Draymond Green (Golden State Warriors).

He’ll lean on the former Warriors teammates to be the leaders of an inexperienced unit that has yet to forge an identity. Durant led Team USA in scoring (19.4) in Rio 2016, so he’ll be asked again to carry the load offensively and be the No. 1 option. Green is the ideal big man at the FIBA level. His versatility will be a huge asset, as well as his defensive acumen. Green and Bam Adebayo (Miami Heat) will rotate at the center position, and could even see time together at certain points.

“We do have all the best players in the league, but these national teams have NBA players, too, who are now No. 1 options and they’re used to playing that role internationally,” Durant told Yahoo Sports.

Despite all its issues, the U.S. remains the favorite in Tokyo. But winning gold is no longer a foregone conclusion. The rest of the world has closed the gap and many international teams are not intimidated by the Stars and Stripes.

“There are more great players all over the world. That’s pretty obvious,” Popovich said. “There are more and more foreign players in the NBA. Every year they go back and play for their home countries as they should. It makes the competition even greater. Makes it more challenging for everybody, including us. But that’s a wonderful thing. Obviously the international has grown, and people love it.”

Team USA point guard Damian Lillard (Portland Trail Blazers) is well aware of the talent outside the U.S. He recently faced one of them in the 2021 NBA playoffs in Facundo Campazzo. The Argentine guard played a huge role in helping the Nuggets eliminate the Blazers in the NBA playoffs.

“These teams are experienced. They’ve spent a lot of time together,” Lillard said. “We are working at becoming a team, still getting our legs under us, getting in shape. We’re not just gonna come out, roll the ball out, and beat these teams. We gotta play the right way … compete. We gotta play to win and give ourselves our best chance. If we don’t, we can get beat.”

Here are six teams that could beat Team USA in Tokyo.

Australia
NBA veteran Joe Ingles wasn’t surprised when his Aussies defeated the U.S. in an exhibition game in Las Vegas. In fact, Ingles said Australia expected to win the game. The Aussies have every right to be confident because they have one of the most talented rosters in the Summer Games. Head coach Brian Goorjian has seven players with NBA experience, including Ingles (Utah Jazz), Patty Mills (San Antonio Spurs), Matisse Thybulle (Philadelphia 76ers), and Aron Baynes (Toronto Raptors). NBA fans know Mills as a role player with the Spurs, but whenever he puts on the Australian national colors he turns into Allen Iverson. Thybulle is a lockdown defender who can “shut off water” in a hurry. Most basketball fans are not familiar with Jock Landale, but they’ll know who he is after Tokyo. Landale, 25, is a well-rounded center armed with a 3-point shot. Landale, who currently plays for Melbourne United in the NBL, would like nothing more than prove to the basketball world that he deserves a shot at the NBA. After finishing fourth in the last two major international competitions, this might be the year the Aussies (ranked No. 3 in FIBA) finally take home a medal.

Spain
Reigning FIBA World Cup champions and No. 2 ranked team Spain possesses the best group of centers and pure point guards in the Olympics. Brothers Marc and Pau Gasol anchor a big Spanish frontcourt that could present plenty of problems for teams in Tokyo. Pau, 41, is playing in his fifth Olympics and would love to finish his decorated career on the national team with a gold medal around his neck. Marc, 36, will be participating in his third Olympics. He won silver in the 2008 and 2012 Olympics. Pau and Marc are not the only pair of brothers playing for Spain. Juancho Hernangomez (Minnesota Timberwolves) and Willy Hernangomez (New Orleans Pelicans) give Spain four quality big men who could wear teams down. Spain also has good depth at point guard with Ricky Rubio (Minnesota Timberwolves), Sergio Rodriguez, and Sergio Llull. All three are capable of running the show. It seems like Rubio has been around the international stage for decades, but he’s only 30 and still in the prime of his basketball life. Llull is one of the top players in the Euroleague and could easily run an NBA offense. At 36 years old, Rudy Fernandez no longer has the legs to attack the rim but he is still an excellent 3-point shooter.

Slovenia
Charles Barkley often refers to ordinary players as JAGs, which stands for Just A Guy. Luka Doncic might the only active player in the world, other than LeBron James, who could take a bunch of JAGs and win a major tournament. Doncic pulled off a stunner during the Olympic qualifying round when he put an entire nation on his back and carried it to its first trip to the Olympic Games. The 22-year-old Dallas Mavericks superstar dropped a triple-double (31 points, 11 rebounds, 13 assists) in the win over Lithuania, sending his home country of Slovenia to Tokyo. “I don’t care about the MVP,” Doncic said. “We won here. We’re going to the Olympics, the first time in our country. It’s amazing. I think every kid dreams about being in the Olympics. I did too. So, here we are. We fought really, really hard, and I think we deserve to be here.” Slovenia may not be a medal favorite, but anything is possible as long as Luka is on the court.

France
Les Bleus returns seven players from its bronze-medal team in the 2019 FIBA World Cup. One of those returning players is three-time NBA defensive player of the year Rudy Gobert. The 7-1 center powered the Utah Jazz to the best record in the NBA and a second-round appearance in the playoffs. Gobert anchors a French squad sprinkled with NBA talent: Nicolas Batum (Los Angeles Clippers), Evan Fournier (Boston Celtics), Timothé Luwawu-Cabarrot (Brooklyn Nets), Frank Ntilikina (New York Knicks). With Gobert protecting the paint and Batum and Ntilikina smothering perimeter players, France will have one of the best defenses in the Olympics. The problem will come on the offensive end. Scoring could be an issue, especially if Fournier struggles from the field.

Argentina
Luis Scola is the last remaining member of the golden age of Argentina basketball. Scola won a gold medal with Argentina — a squad spearheaded by San Antonio Spurs superstar Manu Ginobili — in the 2004 Olympics in Athens. Those glory days a long gone for both Argentina and Scola, but the 41-year-old power forward remains one of the craftiest low-post scorers in FIBA despite having logged thousands of minutes in his basketball career. Scola is surrounded by a talented group of Argentines, including feisty point guard Facundo Campazzo (Denver Nuggets) and 20-year-old sensation Leandro Bolmaro. Bolmaro starred on FC Barcelona in the Euroleague and his draft rights are owned by the Minnesota Timberwolves.

Nigeria
Nigeria stunned the basketball world when it defeated the U.S. 90-87 in an exhibition game in Las Vegas. Then, the Nigerians dominated Argentina in the same Vegas tuneup event. The blowout against Argentina proved that the win over Team USA wasn’t a fluke. The Nigerians are for real and poised to make noise in Tokyo. Head coach Mike Brown — currently an assistant with the Golden State Warriors — is building a formidable program, utilizing the same principles that made the Warriors successful. They share the ball and have some 3-point snipers to space the floor. Three Miami Heat players are on the Nigerian roster: Precious Achiuwa, Chikezie “KZ” Okpala, Nnamdi Vincent. Guard Caleb Agada, who plays in the Israeli league, made a name for himself in Vegas as he lit up Team USA for 17 points. Agada will be on the Denver Nuggets summer league squad.

The Philippines fell to Argentina, 85-81, in a hard-fought FIBA World Cup game in Sevilla, Spain, but Gilas Pilipinas swingman Gabe Norwood provided one of the game’s highlights.

With a little over three minutes left in the first quarter, Gilas point guard Jayson William picked up a loose ball and fed a streaking Norwood on the left wing for a monster slam over Argentina forward Luis Scola. It wasn’t a clean “poster dunk” since Scola appears to be moving out of the way instead of challenging the shot. It was still an electrifying slam: Watch the play:

Norwood’s dunk was part of a big early run by the Filipinos in the opening quarter, as they took a 25-22 lead in an emotionally packed first quarter.  Norwood, who is mostly known for his defense, has been one of the stalwarts for a Philippines squad that could easily be 2-1 instead of 0-3. It lost in overtime to Croatia, 81-78, in the opener and fell to Greece, 82-70, on Day 2.

Norwood, 29, played college ball at George Mason from 2003-07 before getting drafted in the Philippine Basketball Association (PBA) in 2008 by Rain or Shine Elasto Painters. Norwood was the PBA slam dunk champion in 2009, and PBA defensive player of the year in 2010. He is the brother of Denver Broncos wide receiver Jordan Norwood.

The Philippines gave the favored Argentines all it could handle in Day 3 of Group B pool play that went down to the wire, thanks to the 3-point shooting of Gilas guard Jimmy Alapag. In the end, Scola and Argentina made enough big plays down the stretch to escape with a four-point win.

The world may have gained ground on the United States in terms of basketball skill and talent, but the U.S. still has the perfect weapon against international competition: Kobe Bryant.

When the 2012 Summer Games kick off in London, the Americans will be favored to win the men’s basketball competition but they’ll get tested by international powers such as Spain (ranked No. 2 by FIBA), Russia (3), Argentina (4), Lithuania (6), Brazil (7),  and France (8).

Spain is led by the Gasol brothers (Pau and Marc), Russia has Andre Kirilenko and Tim Mozgov, Brazil boasts Leandro Barbosa, Nene and Anderson Varejao, and France is powered by Spurs star Tony Parker. Manu Ginobili and Luis Scola are the top guns for Argentina, the 2004 Olympic gold medalists, while Lithuania features Raptors rookie Jonas Valanciunas and Linas Kleiza.

“It’s a big challenge for us. The rest of the world kinda feels like the gap is continuing to shorten and they feel like they can beat us,” Bryant said. “We’re a fun bunch, joking around and laughing. But we know what’s at stake and we know what we’re representing. Come Olympic time we’re going to be ready to go and going to bring back the medal to the U.S.”

Because the U.S. is not familiar with a lot of the teams they’ll face in London, Bryant believes paying extra attention to detail is very critical to the team’s approach each and every game.

“In the NBA we do a great amount of preparation,” Bryant said. “Against these teams we have to do that even more because we don’t know most of their guys.

“We really have to do our homework and get to know their tendencies.”

Bryant’s supreme confidence was so contagious around the U.S. Olympic team in Beijing he almost single-handedly made everyone forget about the catastrophic loss to Greece in the 2006 World Championship (now renamed the World Cup of Basketball).

When the 2008 Olympic team — which included LeBron James, Chris Paul, Carmelo Anthony, Dwight Howard, Chris Bosh, Deron Williams, and Dwyane Wade — got pushed to the limit by Spain in the gold medal game it was Bryant who pushed right back and carried the U.S. to the finish line.

“He’s the ultimate competitor,” USA Basketball head coach Mike Krzyzewski said of Bryant, who averaged 15 points in the Beijing Olympics. “He’ll do anything to help the team win. And in pressure moments there’s no one any better. He wants the ball or he wants to guard the ball. He was born to be in those moments, and he’s prepared himself for those moments.”

Kobe is one of the few NBA players whose game adapts seamlessly to the FIBA level. Having grown up in Italy, there’s a lot of European influence in Bryant’s game and he can play any style: inside, outside, 3-point shots, dribble drives. He also doesn’t shy away from physical play, which is a big adjustment for NBA players because of the inconsistency in officiating and the amount of contact that is allowed in FIBA tournaments.

At 33, this is most likely Bryant’s last Olympic experience. He would love to add another gold medal to go along with his five NBA championship rings. Like he previously stated, the U.S. will be challenged in London, but as long as the Black Mamba is on his game Team USA is in good hands.

Since stunning a United States team loaded with NBA players in the 2002 World Championships in Indianapolis and capturing the gold medal at the 2004 Olympics, Argentina has been universally recognized as a powerhouse in FIBA competition.

Led by San Antonio Spurs guard Manu Ginobili, arguably Argentina’s greatest player, the South Americans have been a fixture in the medal rounds in the Olympics and World Championships for a decade. But since its fourth-place finish at the 2006 World Championships, Argentina appears to have lost some of its magic as its core group continues to log serious mileage.

Argentina is currently No. 3 in the FIBA world rankings, only behind the United States and Spain. Despite its top-five standing, Argentina is no longer a cinch to win a medal in the 2012 Olympic Games in London as Greece, Lithuania, Turkey, Italy, France and Brazil – the team Argentina defeated in the championship game of the the 2011 FIBA Tournament of the Americas – are hot on its tail and have more young talent in their programs.

Argentina’s big names are still there: Ginobili, Luis Scola, Fabrico Oberto, Andres Nocioni, Pepe Sanchez and Carlos Delfino. Ginobili and Scola are still regarded as two of the best players in the world, but the rest of the squad is looking very old and there seems to be a drought in terms of young talent in Buenos Aires.

Ginobili turned 34 this summer and Scola is 31. At 36, Oberto is way past his prime and even though Nocioni is two years younger than Ginobili his reckless style has caught up with him and his legs seem like they are ready to retire. Delfino is one of the youngest frontline players on the roster and he’s 29.

The 2012 Olympics will more than likely be this group’s last hurrah. Ginobili could try for another Olympic run in four years, but he’ll be 38 and his body may prevent him from playing. Scola doesn’t rely on athleticism so he may still be an effective player in four years. But for the rest of the core players, four years is a very, very long shot.

While the Argentines continue to hang their sombreros on international vets, the other South American hoops powerhouse, Brazil, has rebuilt its program behind a familiar face. Ruben Magnano, who guided Argentina to a gold medal in the 2004 Athens Olympics, was brought in to coach Brazil in 2010. A year later, Magnano has the Brazilians playing their best ball since the Oscar Schmidt era, earning one of the automatic qualifying berths for the 2012 Olympics after reaching the final of the 2011 FIBA Americas.

What was more impressive about Brazil’s run in the FIBA Americas was it reached the final without the help of NBA stars Leandro Barbosa, Nene and Anderson Varejao, who all decided to skip the tournament.

While Argentina leans heavily on Scola and Ginobili on offense, Brazil has a more balanced approach that features the playmaking skills of point guard Marcelo Huertas, who plays for Regal FC Barcelona. Spurs center Tiago Splitter is the only NBA player on Brazil’s roster at FIBA Americas, but he has had minimal impact offensively. The Brazilians have won eight of nine games, including an impressive 73-71 victory over Argentina. Its only loss came against the Dominican Republic in the early round, but it avenged that loss in the knockout round by defeating the Dominicans (led by Al Horford, Francisco Garcia and Charlie Villanueva), 83-76, in the semifinals.

Argentina had a much tougher matchup in the semis, but it managed to squeeze past a rugged Puerto Rico squad (led by J.J. Barea and Carlos Arroyo), 81-79, behind 27 points from Scola and 23 from Ginobili. Scola saved his best for last as he poured in 32 points to power Argentina to a 80-75 win over Brazil in the final.

As long as Scola and Ginobili are healthy, Argentina remains a powerful force and medal contender.

Don’t cry for Argentina just yet.

Even though the South Americans don’t have their best player, Manu Ginobili, in the 2010 FIBA World Championship, the 2004 Olympic gold-medalists are still a threat to contend for a medal in Turkey.

Luis Scola has become the unquestionable leader of the team and he having a very good tournament thus far.

The 6-foot-9 power forward – who recently signed a five-year deal with the Houston Rockets reportedly worth $47 million – is the engine that drives Argentina’s basketball factory. He’s a tough-minded player with an array of low-post moves. And even though Scola is not a very gifted athlete, he makes up for it with smarts and grit.

Scola scored 32 points to help Argentina beat Angola, 91-70, in a Group A game Monday, essentially securing the Argentines a place in the second round at the World Championship. Scola is averaging a tournament-best 28 points per game and a team-best seven boards. It wouldn’t be farfetched to say that Scola is one of the five best players at the FIBA level.

He scored 17 of Argentina’s 23 points in the first quarter against Angola as the South Americans built a three-point lead. He finished the half with 21 points as Argentina led 45-32 at halftime. In an 88-79 victory over Jordan on Wednesday, Scola netted a game-high 30 points on 13-of-18 shooting from the field.

The other half of Argentina’s 1-2 punch is Carlos Delfino. The Milwaukee Bucks guard lit up Angola for 22 points and then scored 18 against Jordan. The streak shooter is capable of carrying Argentina for long stretches and he’s also a very good ball-handler and defender.

Delfino is finally getting an opportunity to shine after playing in the shadows of Ginobili and Andres Nocioni in previous major international competitions. The 6-5 guard is averaging 18 points, five rebounds and almost four assists.

The other Argentine with NBA experience is Fabricio Oberto, who won a championship ring with the San Antonio Spurs in 2007. Oberto spent four seasons in San Antonio and played for the Washington Wizards last season.

Point guard Pablo Prigioni is a veteran guard with plenty of international experience. He leads the team in assists at 4.7 and he allows Delfino to play off the ball, in which he’s more effective.

Argentina (4-0) appears to be on track to finish Group A in first place, with only Serbia standing in the way of a perfect round. Regardless of how it does against Serbia, Argentina will be a tough out in the knockout round.
