Hey Mike,
There is no built-in support for game officials. The media field could certainly be used. My first idea was to add the officials to the Game Info field, which is displayed on the game page. One of the options in the Settings is to show the game page when the game status field is clicked. You can add images, links, videos, whatever to that field.
Speaking of which, that’s what I’d recommend for the match sheets. Scan them, upload them to the media library, add them to the game info field.
Hope that helps.
