The white team seems to comprise older, burlier boys who are all good at soccer, so they naturally have an advantage over the younger and less skilled green team. But the novel also suggests that the white team is kind of missing the point, especially when they win the match but receive less
chittim. The point is, presumably, that each team learns to work together to support all the kids who want to play, from girls to boys who are new to the game. By prioritizing winning, the white team seems to have more in common with corrupt Leopard figures, like Madame Koto—they’re enriching themselves, rather than caring for others.
