If the NFL gets any more physical it will have more in common with wrestling than any other ball based sport, which will definitely change the branding for each team.
Instead of the classic fully clothed New England patriot we'd have a bare chested John Cena, and that racist and outdated redskin's head would be replaced by Hulk Hogan's noggin, to help bring Hulkamania to the gridiron.
Teams like the Chargers who seem to be up for grabs in terms of home city would dig in to their roots with a little help from the Undertaker
And Dwayne "The Rock" Johnson would return to his roots in Miami to become the head of the Miami Rocks. Smells like he's cooking some pigskin!
