Move the Rams back to Los Angeles, the Cardinals back to St. Louis and create a new team for Arizona - “The Arizona Border Jumpers”.
Why even attach a team to a city. Just move ‘em around. “Home Team” is so 20th century.
Or, the Guerillicos.
...and then the Colts could move back to Baltimore and the Ravens (nee Browns) could move back to Cleveland. And then the Tennessee Titans (nee Houston Oilers) move to Houston and the Texans could move to Indianapolis. And finally, the the Cleveland ‘Browns II’ could move to Tennessee.
Or something...
