Brazuca

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.

Seven unheralded stars of this Premier League season

Look, it’s been a crazy year in the Premier League. Leicester City is top by five points, Chelsea is a bottom-half side, and not one of the league’s top three scorers hails from a team in last season’s Top Four.

So it follows that among the league’s other statistical leaders — advanced and traditional — are some surprisingly shining stars.

Or at least they aren’t mentioned a ton. We plan to rectify that here. By no means do we claim these statistical leaders without fault this season, but hats off to the good they’ve done (or, in some cases, the pain they’ve felt).

Most saves in a starring role

You wouldn’t know it from the goal totals these past few weeks, but Stoke City’s Jack Butland has been playing otherworldly between the sticks. His 87 saves lead the Premier League, and the Potters would be in the thick of a relegation battle if he hadn’t shone as brightly.

Ironman

Eleven players have played every minute of their side’s Premier League campaign this season (a 12th, Gareth Barry, has played all but one). Four of those 11 are goalkeepers, and six more are defenders. The only midfielder? Bournemouth’s South African standout Andrew Surman (above).

Top thief, too

Surman is also the league leader in interceptions with 92. The next seven players on the list, headed by Chris Smalling, are all defenders.

The most under-appreciated of the underdogs

Leicester City has been fantastic, and people are quick to name Riyad Mahrez and Jamie Vardy as big parts of the table-topping effort at King Power Stadium. Then, perhaps they’ll say something about goalkeeper Kaspar Schmeichel or defender Wes Morgan.

But how about the Premier League’s leader in tackles. Midfielder N'Golo Kante (right) has 115 tackles, 12 more than second-best Yohan Cabaye of Crystal Palace.

An all-expense paid journey to the massage parlor for…

Five players have been fouled more than 50 times this year, and you need to be around the ball a lot for that to happen. The four also-rans are Southampton’s Sadio Mane, Swansea City’s Andre Ayew, Everton’s Ross Barkley and Mahrez, but the man who deserved to skip to the head of the ice bath line is from Crystal Palace: Wilfried Zaha has been fouled 59 times. And that’s the amount of times the foulers were caught in the act.

Let Newcastle United’s captain climb in second, though; Fabricio Coloccini‘s 47 blocked shots are eight more than runners-up Neil Taylor (Swans) and Christian Fuchs (Leicester).

A man possessed

He hasn’t been heralded like a year ago, and most witnesses would tell you the midfielder’s been playing much worse. No, touches don’t equal success, but Cesc Fabregas‘ 2,027 credited touches are 74 more than the next player despite the fact that he’s the only player in the top four to have started less than 25 matches. He’s also completed 83 more passes than the closest competitor (Surman).

All-around stars

Advanced stats site Squawka uses an algorithm to generate statistics on who just might be the most complete player in the Premier League.

It’s certainly not foolproof, but the best player per-90 minutes would likely surprise you: Mousa Dembele of Spurs (Minimum 15 matches).

As for who’s produced the most when numbers are averaged out over the entire game, one man rises to the top: Ross Barkley.

William Carvalho has been running through the rumor mill for ages, and Sporting Lisbon has made sure they’ll get their due if he ever stops somewhere else.

The Angola-born Portuguese defensive midfielder with 15 caps has extended his contract with Sporting through 2020, a date that carries him through his 28th birthday.

Carvalho is 23 now, and has been linked with loads of big name clubs from Manchester United to Chelsea, Arsenal to PSG.

His new buyout clause is said to be as high as $53 million, and Carvalho hopes his commitment calms his supporters.

“Sportinguistas, I say to you that I am very happy with the deal which I signed up to 2020 and that you will have total effort on my part to be champions.”

Sporting is tied with Benfica atop the Portuguese table, second on goal differential. The club leads third-place Porto by six points, and is still alive in the Europa League. Bayer Leverkusen is up next.

Klinsmann hints at Euro-heavy roster for World Cup qualifiers

If your favorite Major League Soccer players don’t make the cut for Jurgen Klinsmann’s next roster, don’t think you won’t see them in the red, white and blue this summer.

[ JPW: What’s the best XI for USMNT’s World Cup qualifiers? ]

Perhaps it’ll be different for the players who were a part of January camp — stars Lee Nguyen and Steve Birnbaum chief among them — but Klinsmann says the late start of the MLS season can affect fitness for the critical qualifiers home and away to Guatemala.

That means there’s a better chance to see in-form Championship midfielder Danny Williams (above) or Pachuca’s Omar Gonzalez then, say, Orlando City’s Brek Shea or Real Salt Lake’s Kyle Beckerman.

From USSoccer.com:

“We are basically looking all over the place. We monitor all the players in Europe. We monitor all the players in Mexico, and obviously we can’t wait until MLS starts as well. It’s really kind of crucial that we see everybody getting in the best shape possible, everybody getting into a rhythm and making statements.

“Then you say, ‘Is the roster you see at the end of March the same one as Copa America?’ Probably not. The end of March comes early for MLS players. The European players are in the full swing, and also Mexican players because they started already a month ago with Liga MX. So we’ll be monitoring everyone.”

We’ve already covered the obstacle that is the CONCACAF-CONMEBOL Olympic qualifying playoff occurring at the same time as the Guatemala matches, but this is still good news for players in England, Germany and other European locales seeking caps in March.

Klopp on struggling Benteke: “He wants to score and we need him to score”

Jurgen Klopp had his appendix removed this weekend, but it’s doubtful he’s feeling as sore as his big Belgian striker.

Christian Benteke had the opportunity to put himself in the good graces of Liverpool fans with a number of decent chances in Tuesday’s FA Cup loss to West Ham, but couldn’t get the job done.

In one case, Benteke put himself in a prime spot only to lash his shot wide of the post. Instead, he’s now at 11 appearances without a goal (despite ripping nine shots against the Irons).

From the BBC:

“I don’t believe in the easy goal. He has to carry on like this. It’s not the nicest moment in his career but he has to work hard. He wants to score and we need him to score. We will work on it in the days, weeks and months.”

Klopp maintained that Liverpool was “the better team” on the night — counterpart Slaven Bilic disagreed — despite conceding a pair of very similar looking goals.

The game could’ve avoided extra time through Benteke’s boots and body, but he couldn’t find his finish again.

The 25-year-old has seen his goal production drop by nearly half since joining from Aston Villa in the summer, and it’s sure to return… just maybe not under Klopp.
