What I want to know is, how does blitzball not collapse under it's own financial weight? I mean, if you have to generate a giant floating sphere of water, regardless of the laws of physics, your electricity bill must be huge. The smaller teams can't hope to compete, since they can't practice in the sea because of, you know, fish, so they can only book time in bigger stadiums which can only destroy their bank balances, what with the amount the owners of the stadiums will need to charge to ever hope of making money.
