Context: The Oakland Raiders relocation to Las Vegas was a successful effort by the owner of the Oakland Raiders (Mark Davis) to relocate the American football club from its current and longtime home of Oakland, California to Las Vegas, Nevada.  The team is scheduled to begin play as the Las Vegas Raiders for the 2020 National Football League (NFL) season (although a move to Las Vegas could happen as soon as 2019 with Sam Boyd Stadium), playing home games at the Las Vegas Stadium.  NFL team owners voted 31–1 to approve the move, which was announced at the annual league meetings in Phoenix, Arizona on March 27, 2017.  The Raiders became the third NFL franchise to relocate in the 2010s, following the Rams' move from St. Louis, Missouri to Los Angeles, California on January 12, 2016, and the Chargers' move from San Diego, California to Los Angeles on January 12, 2017.
