This plugin will add a tooltip to all Eliteprospects.com profile page links, like players and staff, on your page.
A single script is added to the footer of your pages so your theme need to have the wp_footer() template tag in the appropriate place.
To create links you can use this plugin:
https://wordpress.org/plugins/eliteprospects-player-link/
Please note that this plugin uses an Ajax call to http://api.eliteprospects.com to get the content for the tooltip.
