Underwater football? Now that's getting Tidus's brow to crinkle, halting any immediate answer as he has to think. Remember what football was about, how it would translate into blitzball. Well, for one thing...

"Isn't the big thing about football the running? You couldn't pass between your legs underwater." That's for sure. "I don't know... what's the difference than the shape? Do you ever kick a football?"

He remembers it's more carrying and throwing, but maybe he's forgetting times feet are used for more than moving around the field.
