Jabulani wasn't the worst in that decade of World Cups' balls: Fevernova had the crazy curving ability and was significantly faster than others at the time, Teamgeist is the lowest diameter possible and feels like a rubber ball for kids. To GP: a difference in texture results in a slightly different technique in ball control and trajectories possible due to a friction drag. As for GGP's comment: a professional football player can adapt to a ball in a couple of training sessions.
