Graphic designer Justin Kozisek might be giving us a look at the a grim future where The Walt Disney Company owns every major entertainment powerhouse. Kozisek's NFL helmet concepts bring Marvel's superhero movie mania to everyone's favorite bone-crushing sport. Some of the mash-ups are pretty clever, like the "Oakland Shields" and the "Washington Groots." And for those Tony Stark fans out there, there's the "San Francisco Ironmen." The project was inspired by this pretty neat set of Star Wars NFL helmets. For more Marvel-branded head protection, check out Kozisek's site.
