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


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.

MLS: NYCFC with 3 wins in 3; defending champs TFC point-less

NEW YORK (AP) Ismael Tajouri and Maximiliano Moralez scored 12-minutes apart in the second half and New York City FC opened the season with three straight wins for the first time in the club’s short history with a 2-0 victory over Orlando City on Saturday.

Orlando goalkeeper Joe Bendik misplayed a back-pass that went right to Tajouri inside the 18-yard box and Tajouri took a few touches to the penalty spot for an easy finish in the 62nd minute. After an Orlando giveaway to Saad Abdul-Salaam, Jesus Medina settled it for an oncoming Moralez to slide it home.

NYCFC (3-0-0) was without start David Villa due to a minor injury.

Orlando City (0-2-1), led by NYC’s former coach Jason Kreis (2014-15), has its share of injury problems as well. Striker Stefano Pinho had a right ankle injury last Saturday, leaving on crutches, and playmaker Dom Dwyer will be out for at least two more weeks.

Sacha Kljestan made his debut for Orlando after serving a two-game ban. The club arrived late due to the St. Patrick’s Day parade traffic.

MONTREAL (AP) Jeisson Vargas scored four minutes before the intermission to lift Montreal to a 1-0 victory over Toronto FC in the Impact’s home opener Saturday.

It was the first MLS goal for 20-year-old Vargas and the first win for new coach Remi Garde, who replaced Mauro Biello in December as coach of the Impact (1-2).

Toronto (0-2) played its first game since a rousing victory in the CONCACAF Champions League over Mexican side Tigres. The travel to Mexico may have sapped some energy from the defending MLS champions, who nonetheless started most of their top players.

Garde seemed to catch everyone off guard by starting a three-man backline with former Marseille defender Rod Fanni making his debut in the middle.

It made for a mostly uneventful first half until Saphir Taider intercepted a ball and sent Ignacio Piatti up the middle. Three Toronto defenders focused on the Impact captain, leaving Vargas open on the right side to take the pass and slice a shot inside the goalpost in the 41st minute for their first lead in three games.

Piatti was inside the Toronto penalty area on two more occasions before the break but Nick Hagglund blocked one dangerous shot and another was also turned away.

Eight minutes into the second half, Piatti sent Taider in alone but Alexander Bono pushed the shot.

Toronto threatened in the 64th when Sebastian Giovinco got the ball to striker Jozy Altidore. He lifted a shot over goalie Evan Bush but saw it bounce just wide. Toronto looked to have tied it in the 84th minute when Altidore’s shot got behind Bush and was rolling slowly to the goal line, but Michael Petrasso swept it away at the last second.

Montreal striker Matteo Mancosu, who missed practice this week for what the team called precautionary reasons, didn’t dress.

Midfielder Victor Vazquez, who has had back trouble, didn’t dress for Toronto. Chris Mavinga (suspected sports hernia) was in the lineup but did not start.

Mourinho slams Man Utd players for “lack of desire” despite FA Cup win

Jose Mourinho, voted the manager mostly likely to zig when everyone else in the world is zagging*, laid into his Manchester United players on Saturday despite the fact the Red Devils topped Brighton & Hove Albion to advance to the semifinals of the FA Cup.

*not a real poll that has ever been taken, as far as we’re aware

[ MORE: Spurs advance to FA Cup semifinal | Man United join them ]

The Portuguese boss called out his players for what he deemed “a lack of personality, a lack of class, and a lack of desire” in the 2-0 victory at Old Trafford.

quotes from the Guardian:

“The basic things is to keep the emotional balance to play with that red shirt, which is a heavy shirt to wear. But to feel not comfortable to play, saying, ‘Please Mister, take me from the pitch.’ I felt that. So I have nothing to lose in relation to that. The strong ones will be always the strong ones. The young ones, under pressure and under criticism, will improve or will not improve.

“Matic was an island of personality and quality. But a few of the other guys, I saw them scared to play. Look, I cannot say much more. I think it is in relation with personality, in relation to trust, in relation to class. And you know when the sun is shining, and in football the sun is shining when everything goes well, you win matches, you score goals, everything goes in your direction, every player is a good player and every player wants to play and every player wants the ball and every player is confident to play and every player looks amazing.

“When it is dark and cold and that in football means a period of bad results or a bad result like what happened to us a couple of days ago, not everybody has the confidence and the personality to play really. Because to be on the pitch and touch the ball every five minutes, anyone can do it but to be on the pitch and say: ‘Give me the ball because I want to play,’ that is a little bit more difficult. Not all of them were able to do it.”

As for 21-year-old Scott McTominay, Mourinho singled him out for criticism not only in the public forum, but in the locker room after the final whistle:

“You have the kid that didn’t play well at all. I told him already, he was the first one I spoke to individually in the dressing room. And instead of being critical with him, I was positive with him saying: ‘You played very bad but you did the basic things that one player has to do.'”

This is year two of Mourinho’s reign at Old Trafford, and if the signs of fractures between manager and players are beginning to sound all too familiar, one should be reminded that Mourinho only signed a new contract to remain at the club through 2020 (with a further option) in January.

SPAL 2013 0-0 Juventus

Just one week after going top of the league with a game in hand, Juventus slipped up away to 17th-place SPAL on Saturday and left the door ever so slightly ajar for second-place Napoli in the title race.

Juve had 65 percent of possession on the day and out-shot SPAL by a count of 12-3 (3-0 on target), but the likes of Paulo Dybala, Gonzalo Higuain, Douglas Costa and Miralem Pjanic couldn’t beat 20-year-old goalkeeper Alex Meret (on loan from Udinese).

Massimiliano Allegri’s side now leads Napoli by five points, but the game in hand now belongs to the chasers, who host 13th-place Genoa on Sunday with a chance to cut the deficit to just two points with nine games remaining. Just when it seemed crystal clear and a foregone conclusion Juve would wrap up their seventh straight Serie A title, newly promoted SPAL helped to make things quite interesting once again.

Jose Mourinho has come under heavy scrutiny in recent days and weeks, as his Manchester United side crashed out of the Champions League this week and continue to trail runaway Premier League leaders Manchester City by 16 points, yet the Portuguese is perhaps just 180 minutes from finishing the 2017-18 with a major trophy anyway.

Man United got the best of Brighton & Hove Albion, to the tune of 2-0 at Old Trafford on Saturday, to book their spot at Wembley Stadium in the semifinals of the FA Cup. Romelu Lukaku scored the winning goal not long before halftime, with United grinding out another laborious result with superstars Paul Pogba and Alexis Sanchez glued to the bench for the whole of 90 minutes.

United enjoyed a healthy 61 percent of possession in the game, but were out-shot by the 12th-place side in the PL by a sizable margin, 16-8 (4-2 on target).

Lukaku’s rampage through the FA Cup continued in the 37th minute, as the big Belgian striker bagged not only his 23rd goal of the season in all competitions, but his fifth of the tournament thus far and extended his record of having scored in each round to four games.

Nemanja Matic floated a cross from the let side of the box to the back post, where Lukaku had created a yard or two of space for himself. Tim Krul didn’t come out to catch it, and Lukaku headed it just under the crossbar to give the Old Trafford faithful reason to smile again.

[ PREVIEW: Who will join Spurs, United at Wembley?

It was Matic who got on the end of another back-post ball, this one from an Ashley Young free kick, in the 84th minute to put United two goals ahead and secure the club’s second FA Cup semifinals appearance in seven seasons (United enjoyed a run of five final-four appearances out of eight in the years prior).

Tottenham Hotspur, who trail United by four points in the race for second in the PL, were the first side to advance to this season’s semifinals by winning 3-0 away to Swansea City on Saturday.
