Michael Peter "Micky" Spilotro (September 12, 1944 – June 14, 1986) was the brother of Anthony "Tony the Ant" Spilotro and was an associate of the Chicago organized crime organization referred to as "The Outfit".
Antonino Joseph "Tony" Accardo (born Antonino Leonardo Accardo; April 28, 1906 – May 22, 1992), also known as "Joe Batters" or "Big Tuna", was a longtime American mobster.
 In a criminal career that spanned eight decades, he rose from small-time hoodlum to the position of day-to-day boss of the Chicago Outfit in 1947, to ultimately becoming the final Outfit authority in 1972.
 Accardo moved the Outfit into new operations and territories, greatly increasing its power and wealth during his tenure as boss.
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.
 The Raiders' move to Las Vegas comes after years of failed efforts to renovate or replace the Oakland–Alameda County Coliseum, which has been rated by multiple sources as one of the worst stadiums in the NFL.
Joseph Ferriola (March 16, 1927 – March 11, 1989), also known as, "Joe Nagall," "Mr. Clean" and "Oscar," was an American mobster who helped run the Chicago Outfit, from 1985 to 1988, after Joseph Aiuppa and John Cerone went to prison for skimming Las Vegas casino profits.
Anthony John Spilotro (May 19, 1938 – June 14, 1986), nicknamed "The Ant", was an American mobster and enforcer for the Chicago Outfit in Las Vegas, Nevada, during the 1970s and 1980s.
 His job was to protect and oversee the Outfit's illegal casino profits (the "skim"), when some of the casinos were run by Frank Rosenthal.
 Spilotro replaced Outfit member Marshall Caifano in Las Vegas.

Gambit is an American television game show based on the card game blackjack, created by Heatter-Quigley Productions.
 The show originally ran on CBS from September 4, 1972, to December 10, 1976, and was recorded at CBS Television City in Studios 31, 33, 41, and 43.
 On October 27, 1980, NBC revived the show as "Las Vegas Gambit", as a replacement for "The David Letterman Show", and kept it on its schedule until November 27, 1981.
 As the title implied, this edition of "Gambit" was recorded in Las Vegas with the Tropicana Las Vegas, which had previously hosted "Dealer's Choice" and later hosted "Let's Make a Deal", serving as the show's base.
 Both versions were hosted by Wink Martindale and announced by Kenny Williams.
 Elaine Stewart was the card dealer for the CBS version, while Beverly Malden filled this role for the first half of "Las Vegas Gambit", and was later replaced by Lee Menning.
The Cohen crime family, or the Siegel crime syndicate, was an Italian-American Mafia / Jewish Mafia crime family created by New York Jewish American mobster Benjamin "Bugsy" Siegel in the early 1930s.
 Siegel ran Los Angeles and later Las Vegas' illegal gambling and prostitution rings with his lieutenants Mickey Cohen, David Berman, Harold "Hooky" Rothman, Moe Sedway and boss of the L.A. family Jack Dragna.
Benjamin "Bugsy" Siegel (February 28, 1906 – June 20, 1947) was a Jewish American mobster.
 Siegel was known as one of the most "infamous and feared gangsters of his day".
 Described as handsome and charismatic, he became one of the first front-page celebrity gangsters.
 He was also a driving force behind the development of the Las Vegas Strip.
 Siegel was not only influential within the Jewish mob but, like his friend and fellow gangster Meyer Lansky, he also held significant influence within the Italian-American Mafia and the largely Italian-Jewish National Crime Syndicate.
