Adidas promises a better World Cup ball
June 12 , 2014
Players complained about the World Cup ball in 2010 since it didn't seem to move right. Brian Palmer of the Washington Post mentioned that the Adidas Jabulani had eight panels and this year it will only have six.
Palmer notes that the ball should move more predictably this year and two players have already praised it.
Moreover, the Los Angeles Times mentions that Japanese researchers have said good things about it as well.
