A quick note about Blitzball: I intend to cover this in much more detail later -- indeed, I have several feature articles in the works that may or may not appear here -- but I want to make a quick point based on the scene with Wakka, Tidus, and the Besaid Aurochs. It would make sense that, in a highly physical and contact-oriented sport like Blitzball, each team has substitutes. However, this is not seen in any team other than the Tidus-managed Aurochs that this is the case. Substitutions are entirely absent, except for the Tidus-Wakka change during the Luca Goers match, and that does not seem to be an official action -- despite time stopping for it.

So if we assume that substitutions are not endorsed by the Spiran Blitzball Association, then we must ask the question: what the hell does Wakka think he's doing letting some stranger on the team? Botta worries that he might be warming the bench, but we know that Tidus is a forward so unless Wakka plans on sitting out during his last ever tournament, it's Datto who's warming the bench indefinitely. I know he's the coach and captain, but Wakka seems like the kind of person to let the Aurochs weigh in on team decisions, and the Aurochs seem like the kind of close knit team that would decide things as a unit. Even though they were obviously impressed with the skills that Tidus has, it's still all very out of the ordinary.
