Right, and again, I think this is just because it’s very difficult to easily and succinctly explain the notion of predictivity to the general public. Maybe it’s not even just the “explain” part, because I don’t doubt that it’s possible to do (though it still appears difficult).
Frankly, most people just don’t CARE about predictivity. That’s not the point for most sports fans. They want to know what happened and why, not so much what is going to happen. Knowing the future takes the fun out of it. That’s why people still watch sports live, rather than just watching a recording after the fact.
Heck, that’s why people hate sports analytics. We’re literally trying to take the “anticipation” away.
