Behind the Brazuca: NBC’s extensive research hints less “knuckle-ball” in Brazil, NASA agrees

3 Comments

After our extensive research it seems as though we can at least guarantee one thing at the 2014 World Cup in Brazil… a better soccer ball to play with.

Cast your minds back to the 2010 World Cup and the debacle that was the Jabulani ball which swerved and dipped all over the place to resemble a beach ball, rather than the ball of choice for the worlds most prestigious soccer tournament.

But fear not, the Brazuca — which was unveiled by FIFA last week before the 2014 World Cup draw — won’t be a distant relative to the Jabualni. It will be, well, more normal. I’m sure goalkeepers of all 32 nations who’ve qualified are now breathing a huge sigh of relief.

For all the details on the new ball, we share with you the incredible in-depth study from Ben Popken for the Consumer News at NBC Business. Ben takes up the story as a Japanese University and NASA break down the science behind the ball, which will be kicked around to either crush or ignite the dreams of billions of soccer fans across the globe next summer.

Over to you, Ben.

The Jabulani curse is lifted.

Any knuckleballs at the 2014 World Cup should be mostly intentional, according to new independent wind tunnel results by Japanese university researchers.

The researcher’s data shows the new Adidas-designed Brazuca matchball for the 2014 World Cup is less likely to swerve at goal strike speeds, meaning there shouldn’t be a repeat of the maddeningly erratic balls at the 2010 World Cup. During those games, goalkeepers and outfield players alike accused the Jabulani matchball, with its glossier texture, asymmetrical panels, and shorter panel bonds, for voodoo shots and an early tournament goal drought.

At the University of Tsukuba in Japan, sports engineering researchers mounted soccerballs in a wind tunnel, blasted them with air, and measured what happened.

Now, in aerodynamics, for every surface there’s an airspeed at which the air flowing over it switches from smooth to turbulent, what’s called the “critical Reynolds number,” and can lead to the sudden veering in flight known as “knuckle-ball.” But in the tests the Jabulani’s occurred at higher speeds than the mid-30’s mph seen on older balls.

In fact, it happened at 53 mph, right in the 50-60 mph range professional goal strikes and corners start at.

That could explain a few things that happened in South Africa.

This time around, those strikes should power through the knuckle-ball effect. In the wind tunnel tests, the Brazuca’s critical Reynolds number occurred at 38 mph.

Those results are more comparable to the Tango 12 ball, itself a player favorite and one of the balls on which Adidas based the design for the Brazuca.

“The asymmetry of ball panel location is one of the reasons to produce knuckling effect,” said Dr. Takeshi Asai of the University of Tsukuba’s Institute of Health and Sports Science. “Ordinarily, the asymmetry of ball panel increases, as the ball panel number decreases.”

That means the Brazuca’s six interlocking boomerang panels, fewer than the Jabulani’s eight, both of which are fewer than the classic 32 pentagon and hexagon panels, could normally pose a problem.

“However, the total distance of the panel bonds or seams of the Brazuca is longer than that of Jabulani,” said Aasai, 10.89 feet worth compared to the Jabulani’s 6.49. “Therefore, I think the strength of the knuckling effect may be slightly lower than that of Jabulani.”

A NASA researcher agrees.

Rabi Mehta, Branch Chief at NASA Ames Research Center and an aerodynamics expert who previously evaluated the Jabulani, has examined close up photos of the new ball. He thinks the Brazuca will gain stability over the Jabulani from its longer seams, identical interlocking panels, and a surface that features a slightly raised texture similar to a basketball’s.

“My theory is that the effective roughness compared to the previous ball is increased, which means the speed at which it knuckles is lower,” said Mehta.

That’s good news for Adidas, which has spent years making sure the Brazuca isn’t Jabulani part 2. They kicked the ball over and over with a robot leg and measured its flight, interviewed hundreds of professional players, a third of which were non-Adidas sponsored, and even snuck the Brazuca in as the matchball for the U20 World Cup.

“While we can’t comment on independent research, we can say that Brazuca is our most tested ball ever,” said Adidas spokeswoman Lauren Lamkin. “We conducted two-and-a-half years of testing in 10 countries across three continents involving more than 600 players and 26 teams to ensure that Brazuca exceeds all performance standards.”

However, she said, “It is correct that the seam geometry aids in flight stabilization.”

Hopefully, all this science leads to surer shots and more exciting gameplay in Brazil come this June. If not, at least it will be harder to blame the ball for it.

Premier League top scorers: Who is leading 2022 Golden Boot race?

For those tempted to write off Erling Haaland’s historically-hot start to life as a Premier League striker, we get it: There’s something rather dull about not wondering the identity of the 2022 Golden Boot winner, but just the number of his final tally.

Haaland’s Premier League-leading 14 goals from eight games has him seven goals clear of the next closest challenger: Tottenham’s Harry Kane.

His third hat trick of the season, joined by three Phil Foden goals in Man City’s 6-3 derby win over United, keeps him on pace for more than 60 goals this season, a mark that would

And even though Haaland is currently overperforming his expected goals total, it’s already becoming clear that projecting him for the Premier League record is not farfetched at all.

Take a look at these digits. Haaland isn’t just punching in goals; He’s made an almost seamless transition to Pep Guardiola’s system, producing chances for others in addition to his powerful self-positioning.

Haaland is unlikely to hit even 50 goals given the schedule congestion to come for Man City, but the Premier League record is very well under assault

Mohamed Salah holds the 38-game season record with his 32 goals scored for Liverpool during the 2017-18 season, while Newcastle’s Andy Cole and Blackburn’s Alan Shearer bagged 34 during 42-game seasons in the 20th century’s final decade.

Haaland also could topple the record for goal involvements (goals plus assists) in a single season, including beating the 42-game record. Alan Shearer put up 47 over 42, while Thierry Henry holds the 38-game record with 44.

Other records that Haaland could legitimately tie or topple:

  • 30 goals in a first Premier League season (Kevin Phillips, Sunderland, 1999-2000)
  • Goals in 24 different Premier League matches (Salah, Liverpool, 2017-18)
  • Most goals in a Premier League match (Five tied with five)
  • 11-straight Premier League games with a goal (Jamie Vardy, Leicester, 2014-15)

Read on to see the latest Premier League goal totals for the 2022-23 season, as Haaland looks to claim a Golden Boot in his first PL season.

Kevin De Bruyne’s gaudy assist numbers give rise to any number of considerations, and we have to wonder if the Manchester City star has ever wondered if the Premier League record would be his in a world in which Jose Mourinho found better use for him at Chelsea.

De Bruyne’s eight assists this Premier League season are double his closest competitors — teammate Bernardo Silva and Arsenal’s Bukayo Saka — to give him 94 for his career. That’s tied for fifth all-time with Dennis Bergkamp, 72 behind record holder Ryan Giggs.

The Belgian star, 31, arrived at Chelsea from Werder Bremen at the age of 22 and managed only 425 in a half-season before being offloaded to Wolfsburg. Back in the Bundesliga, De Bruyne got six assists the rest of the way before setting up 21 goals the next season to set up a move to Man City.

He’s since won the nascent Premier League Playmaker of the Season Award twice, including a 20-assist 2019-20 season, and he’s on pace to make it three of six. Harry Kane, Mohamed Salah, and Eden Hazard have also won the award, which is only five years old.

De Bruyne also led the Premier League in assists in 2016-17, the year before the league but a name on the honor.

His stats hint that there’s more to come, as ‘KDB’ is creating a gaudy 3.95 chances per 90 minutes. After a season in which he scored 15 times with eight assists, De Bruyne is back taunting those who’d dare chase him in terms of setting up goals (Some guy named Erling Haaland is helping…).

Take a look at De Bruyne’s shining stats, and read on to see who’s chasing him in a list of the Premier League assist leaders for the 2022-23 season.
