Broadcast media outlets fail at that. I don't know much about sports but even I can tell that people on TV are speaking in vague generalities so they can never be proven wrong. I get told that the team that lost "didn't want to win" as if people getting paid millions a year to win at sports aren't motivated.

When people are afraid of being proven wrong above all else, they avoid making any substantive claims. If someone isn't afraid of that, they'll make more interesting predictions I can't get elsewhere, and eventually it'll be a more enjoyable product because I can make fun of that person for being wrong.
