How Do I Change the Logo for an NFL.com Fantasy Team?
As of 2014, logos for fantasy football teams on the National Football League's website can be changed under the Team Settings page. Choose from over 200 pre-loaded images for a team logo, or upload your own custom logo.
In addition to changing logos, on the Team Settings page, you can alter your team's name, change your time zone, verify your email address, invite others to co-own or co-manage a team with you, or customize your live scoring settings. The link to the Team Settings page is found on the My Team page, which is the main page for managing your fantasy team.
