There are two aspects of this:

1. If all superbowl-related articles used an extraction mechanism that links wikipedia with wikidata, then only the wikidata entry needs updating and all these articles get updated automatically. 2. That wikidata update I mentioned was manual, but a lot of data in Wikidata is updated automatically (e.g. births and deaths from some databases, city population counts etc.), so some things get updated across the board automatically. That's a source of pushback against this - articles being updated automatically, so bad actors can change a lot of things at once.
