UPDATE: The NFL backs down … sort of.
NFL Fail.

Fleurty Girl received a cease-and-desist letter from the NFL because of her #WHODAT shirts.

Now I get that using the rather Saints-ish version of the fleur-de-lis is a problem (but dude, it’s a fleur-de-lis. Get a stronger trademark). But I hope the NFL isn’t seriously claiming rights to “Who Dat?” too.
