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.
