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.

VANCOUVER, British Columbia (AP) Cristian Techera scored three second-half goals and the Vancouver Whitecaps overcame several defensive errors to tie the New England Revolution 3-3 on Saturday.

Techera completed the hat trick in the 74th minute off a pass from striker Yordy Reyna.

The Whitecaps (4-5-5) are winless in five games and have just one victory in their past nine matches (1-4-4). New England is 5-4-3.

Vancouver trailed 2-0 early in the second half.

Whitecaps defender Aly Ghazal had an own goal and made a poor pass that helped set up a goal by New England’s Teal Bunbury. Another Revolution goal came after defender Sean Franklin mishandled a ball.

Techera made it 2-1 in the 49th minute off a cross from Marcel de Jong. Russell Teibert set up Techera again two minutes later, with Techera scoring on a header after goalkeeper Matt Turner stopped the first shot.

Bunbury gave New England a 3-2 lead in the 59th minute after Ghazal’s weak pass was picked off.

Cristian Penilla also scored for New England.


ORLANDO, Fla. (AP) — Alan Gordon broke a tie in the 82nd minute and the Chicago Fire beat Orlando City 2-1 on Saturday night.

Gordon settled Bastian Schweinsteiger’s cross with a couple of touches at 25 yards from goal and fired a rocket into the upper right corner past goalkeeper Joe Bendik’s outstretched hand.

Chicago’s Mohammed Adams was sent off in the 89th minute for violent conduct, but the Fire (4-6-2) held on from there, including six minutes of stoppage time, to end a two-game losing streak.

Orlando City (6-5-1) has lost three straight after winning six in a row.

Aleksandar Katai gave Chicago the lead on a free kick in the 13th minute.

Cristian Higuita tied it for Orlando City in the 28th minute, slotting a right-footed shot inside the far post after getting sprung free by Chris Mueller’s short pass to the right side of the penalty area.

Patrick McLain had four saves for his first MLS win.

Walker hopes young England squad proves more “streetwise”

Kyle Walker, who finds himself one of England’s youthful elder statesman ahead of next month’s World Cup, believes Gareth Southgate‘s 23-man squad has a “different vibe” around it and hopes that vibe will aid in galvanizing the Three Lions when they arrive in Russia.

Iterations past, as Walker sees it, lacked a certain “streetwise” sense about them; not that they weren’t always a hard-working bunch, but that they lacked the understanding to play smarter, not harder, in certain moments.

Walker, who missed out on the 2014 World Cup due to an injury suffered not long before the tournament in Brazil, feels he’s matured a great deal during his first 12 months at Manchester City, under Pep Guardiola, and he’s ready to impart some of that wisdom on the rest of the squad, with the help of a few of his Man City teammates — quotes from the Guardian:

“The whole vibe around England now is completely different. It is a younger set of players and we are taking huge steps in the right direction but we still probably need to get more streetwise.

“English footballers are honest, they will run for 90-odd minutes, but that is not always what you need. Sometimes you need to rein back a bit and try and control the game with your passing.

“When we come up against Belgium, say, it could be a deciding game but we need to realize that we don’t have to score in the first 10 minutes. If you can control the game you can wait until the 80th minute or longer if necessary. I’m trying to bring that calmness from Manchester City, and so is John [Stones].

“I’ve adapted my own game a bit since changing club. I stay back a bit more. When I was at Tottenham the fans wanted attack, attack, attack but, if you send too many bodies forward, you are liable for the counter. With England we are working in training on controlling situations a little better. If we can make it work on the pitch we will hopefully have a good tournament.”

Whether or not Walker plays right back — where he’s spent the majority of his career — or on the right side of a back-three, he’ll be second-most senior member of a defensive unity which is nearly untested in major tournaments.

Of the nine defenders chosen in the squad, only Gary Cahill (58 – the only player over 40) and Walker have made more than 30 appearances for England. Of the 23 players chosen throughout the entire squad, the average number of caps won is 19.5.

Platini vows to return to soccer after “end of long nightmare”

PARIS (AP) Banned former UEFA President and FIFA vice president Michel Platini says he is planning to return to soccer after Swiss federal prosecutors confirmed he was not being charged in an investigation into possible financial wrongdoing.

Platini says in a statement it’s “the end of a long nightmare for my family and those close to me.”

Since September 2015, the former France midfielder had the status of “between a witness and an accused person” in criminal proceedings opened against then-FIFA President Sepp Blatter. No criminal case was ever opened against Platini.

The evidence related to Blatter authorizing FIFA to pay Platini $2 million in uncontracted back salary in 2011.

FIFA’s ethics committee also investigated Platini’s request to FIFA for pension contributions he was not entitled to. It was agreed by Blatter and added more than $1 million to Platini’s retirement fund.

Platini was eventually banned for four years, through October 2019. Both he and Blatter denied wrongdoing but Court of Arbitration for Sport judges refused to overturn his ban and that of Blatter’s.

The case meant Platini was removed from the UEFA presidency and he was barred from trying to succeed Blatter as FIFA president in 2016.

Platini, a former France captain and coach, says “I will come back: where, when, how? It’s too early to say. But I will come back into football.

“Because football is my life and I deny anyone the right to deprive me of my life,” the 62-year-old Platini says.

Neymar appears in good shape after first week with Brazil

TERESOPOLIS, Brazil (AP) Neymar finished his first full week of training with Brazil on Saturday in apparent good shape ahead of the upcoming World Cup after foot surgery.

The striker continued his recovery, dribbling and passing at high speed in Brazil’s last training session on home soil before the national team sets up camp in London on Monday.

The Brazilian has been recovering from right foot surgery in March.

Earlier in the week, members of Brazil’s coaching staff said Neymar was fit to train but they tried to reduce pressure on him by saying it would take time until he delivered his best performances.

Left back Filipe Luis said Neymar did well in training but still needs to forget the injury.

“I had a serious injury in 2010 and I came back with fear. In the first chance I had in a game, I went with it all so I could lose that fear. I saw it didn’t hurt and I just forgot,” Luis said. “It will be the same with Neymar, the first time an opponent kicks him … he will forget it.”

In the first training session in Teresopolis, outside Rio de Janeiro, Neymar occasionally dragged his right foot onto the pitch. On Thursday he took his right boot off, sat down for a few minutes and looked upset. Once the football was underway, he seemed as fit as his teammates despite accidentally kicking the pitch with his injured foot. He soon afterward got back in action.

In the first and only Brazil open training session, with fans screaming his name on the sidelines, a playful Neymar nutmegged right-back Danilo and flipped the ball over Luis’ head.

Throughout the week Neymar showed his finishing was sharpening, especially from close range.

After Saturday’s training Neymar welcomed his girlfriend, actress Bruna Marquezine, and family members to the Granja Comary training ground.

With Brazil players off duty for the rest of the day, Neymar is expected to take some teammates back to his mansion in Mangaratiba, near Rio.

The 20-strong squad will meet again Sunday morning at the Brazilian football confederation headquarters in a visit to their museum.

Players then travel to London hours later and will set up camp until June 8 at Tottenham’s training ground.
