Advice on development Best Practices

Hi I would like your opinions on what you think the best process could be for developing a part of a site.

On the home page of this site (demo server) http://goo.gl/XGQ5O9 there is a section under the slider with the title "Fixtures - 18 April" that has two cells below it. see this image example http://screencast.com/t/46YhLuxzzL

Currently I am managing these updates but will be handing it over to the client. The Fixtures area is created through the wordpress editor using a table with assigned classes for css.

My concern is if the client in error deletes the table they cannot recreate it with the classes for styling.

I have thought of developing a custom post type for the fixtures this way a client could not delete the table.

What are your opinions to develop an area for the fixtures, if possible I would like to still keep the wordpress editor without creating a custom post type

Thanks
Arthur
