How is it set up though? I feel I could battle harden a WP setup with those needs. Disable most of the admin interface. Just let them access what they need.

How is it set up though? I feel I could battle harden a WP setup with those needs. Disable most of the admin interface. Just let them access what they need. Announcements, schedules, and where to play - stored as ACF records on a page/post and displayed with a custom template/loop. Slim down the admin interface to just CRUD for those items.
