There's no doubt that kids will be happy if you give them a shiny new football. They'll also be happy if you give them a secondhand t-shirt or new pair of shoes. That makes for lots of donor 'feel good' and nice photos on your Facebook page, but that doesn't make it good aid.
If the priority here is to do something helpful for the developing world, and that's why they're willing to put all the required effort and money into this project, then why not start by asking the developing world what their pressing problems are? Ask a few developing country governments and see how many of them report a lack of good footballs as a pressing problem.
When people don't ask questions like that it's usually an indication that the aid is more about the donor than the recipient. This project sounds a lot like TOMS Shoes Buy One Give One which has been frequently criticized for being a donor oriented initiative with little long term benefit . It might sound completely harmless to hand out free shoes to kids, but it ends up undermining local producers and sellers, and perpetuates a 'handout' aid culture.
There are no local producers of indestructible soccer balls. What will this undermine? I'm not trying to defend all comparable initiatives. I'm trying to understand the opposition to this particular one. Tom's shoes is a completely different issue.
Further, one cannot live on soccer balls no matter how indestructible. We aren't talking about giving out food for 10 years and then expecting someone to provide for themselves. We're talking about something that, where livelihood is concerned, is completely useless. A toy. I really do not see how giving a toy could create or perpetuate an expectation of handouts for any "real" aid. And I also don't see how handouts of toys can do any harm. I'm open to being corrected. I'm just letting you know why your argument hasn't convinced me yet.
Finally, asking someone what they want is not necessarily the best way to determine how to help them. I'm not suggesting that this is the best way to help. I'm just pointing out that, "If you want to help, ask, then do that," isn't foolproof.
Your argument seems to be that since footballs don't contribute to development, then this project won't do any long term harm or good. That just seems like a great shame to me - if we're going to invest all this money and effort, can't we find something to do that brings long term good? And something that won't perpetuate the common western view of places like Africa of hungry kids needing handouts.
But you're right that asking won't always yield the best solutions - let's say then you should spend sometime getting to know the place you want to help. Not convinced that has happened with this project.

Poor people are karma producers. Rich people are karma consumers. Rich people buy karma from poor people to make themselves feel better.
