I started adding each team kit design to their respective pages and I said to myself: Why stop there? So I took the Souhoku High Bicycle Club page and added some sections that I think are relevant to explain the "why and how" of each team, but I'm stuck: Yowamushi Pedal is a story and as every story it develops over time, so teams are also subject to changes and I can't find a proper way to organize those changes.
I proposed the "Old Team/Current Team" lists but it doesn't convince me it's the right way, because we know things are going to change (are changing? *spoiler*) eventually. There must be a way to make it more maintainable and sustainable over time.
