Jack Louis Del Rio Jr. (born April 4, 1963) is head coach of the Oakland Raiders of the National Football League (NFL).
 A linebacker for four NFL teams between 1985–1996, he played both football and baseball for the University of Southern California Trojans.
The 2017 Oakland Raiders season is the 58th overall season of the Oakland Raiders franchise, the franchise's 48th season in the National Football League, their 24th season since their return to Oakland, and the third under head coach Jack Del Rio.
 The Raiders are looking to win their first AFC West title since 2002 and the Super Bowl for the first time since 1983, when the club was still in Los Angeles.
 The Raiders began the season on September 10 at the Tennessee Titans and will finish the season December 31 at the Los Angeles Chargers.
 The Raiders, as they did in 2016, will play one home game in Mexico City, this time against the New England Patriots.
The 2016 Oakland Raiders season was the 57th overall of the Oakland Raiders franchise, the franchise's 47th season in the National Football League, their 23th season since their return to Oakland, and the second under head coach Jack Del Rio.
 The Raiders improved on a 7–9 campaign in 2015 and finished with a winning record for the first time since 2002, finishing the regular season with a 12–4 record.
There have been 20 head coaches for the Oakland Raiders of the National Football League (NFL).
 The Raiders franchise was founded in Oakland, California in 1959 and became the eighth member of the American Football League (AFL) in 1960 as a replacement for the Minnesota Vikings, who had moved to the NFL.
 The Raiders joined the NFL in 1970, after the AFL–NFL merger.
 They played in Los Angeles between 1982 and 1995, before returning to Oakland.
 As of the end of the 2015 season, the Raiders have played 852 games in a total of 56 seasons in the AFL and NFL.
 In those games, two coaches have won the Super Bowl with the team: John Madden in 1976 and Tom Flores in 1980 and 1983.
 One coach, John Rauch in 1966, won the AFL Championship.
 Three other coaches, Art Shell, Jon Gruden and Bill Callahan, have also taken the Raiders to the playoffs.
 Callahan led the Raiders to the Super Bowl.
 He did this in his first year as head coach of the team.
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.
Gil Haskell (born September 24, 1943) is a long time National Football League (NFL) coach and the former offensive coordinator of the Seattle Seahawks.
 He began his career in the NFL as a ball boy with the San Francisco 49ers while his uncle Dr. William O’Grady was a part owner of the franchise.
 Coach Haskell grew up in St. Brendan's Parish in San Francisco, graduated from St. Ignatius High School in 1961, played at San Francisco State, and then was head coach at St. Ignatius from 1973–1977.
 Haskell then left for USC, spending 5 seasons as an assistant coach.
 He broke into the NFL as a coach in 1983 with the Los Angeles Rams, coaching special teams, running backs and tight ends for 9 seasons.
 In 1992, he joined the Green Bay Packers where he became part of Mike Holmgren's staff for the first time as a running back coach and wide receiver coach.
 When Holmgren left Green Bay for the Seattle Seahawks in 1998 Haskell accepted the Offensive Coordinator position with the Carolina Panthers.
 The next season, he reunited with Holmgren in Seattle in the same role.
 He has indicated that he would like to be a head coach in the NFL and even launched a low key campaign for the Oakland Raiders position when the Raiders fired Norv Turner after the 2005 season.
 That position was eventually filled with the hiring of Art Shell.
Ken Herock (born July 16, 1941, in Pittsburgh) was an American college and professional football player who played tight end.
 He played collegiately at West Virginia and professionally in the American Football League, where he played for the AFL Champion Oakland Raiders in the second AFL-NFL World Championship Game, held after the 1967 season.
 He attended Munhall High School in Pittsburgh.
 His six-year pro career was spent with the Oakland Raiders, who he helped win the AFL title, the Cincinnati Bengals, and the Boston Patriots.
 After his playing career ended, Herock was a player personnel executive in the NFL with the Raiders, the Tampa Bay Buccaneers, and the Atlanta Falcons.
 He is known for trading Brett Favre from the Falcons to the Green Bay Packers at the urging of head coach Jerry Glanville.
Monte C. Johnson (born October 26, 1951) is a retired American football player.
 Johnson, who never started in college, was selected by The Oakland Raiders during the second round of the 1973 NFL Draft as the 49th player selected overall.
 Johnson attended the University of Nebraska and won two National Championships with Nebraska, and one Super Bowl (XI) with the Oakland Raiders.
 Johnson was injured in the 1980 season, and as a result did not play in Super Bowl XV, when the Raiders defeated the Eagles.
 Johnson considers the 1977 AFC Divisional playoff game against the Baltimore Colts, a game known as, "Ghost to the Post", to be his greatest game.
 Johnson finished the game, which went to double overtime, with 22 tackles despite suffering a broken vertebra during regulation.
 Johnson retired from professional football in 1981, after eight seasons in Oakland, as a result of a career-ending knee injury he incurred early in the 1980 season.
Joseph John Bugel (born March 10, 1940) is an American former football coach and college player who held a variety of coaching positions at the college and professional levels of the sport over his 46-year career.
 Although he was twice a head coach in the National Football League (NFL), he is widely acknowledged as one of the great offensive line coaches in NFL history, most notably for the Washington Redskins from 1981 to 1989 and from 2004 to 2009.
 He served as offensive line coach or assistant for the Detroit Lions 1975–76, the Houston Oilers 1977–80, Washington Redskins 1981–89, Oakland Raiders 1995–96, San Diego Chargers 1998–2001, and the Redskins again since 2004.
 He was also head coach of the Phoenix Cardinals (1990–93) and Oakland Raiders (1997).
 As head coach of the Phoenix Cardinals, and the Oakland Raiders, Bugel compiled a record of 24 wins against 56 losses over five full seasons.
 He is best known for the creation of "The Hogs"—the nickname he penned for his offensive line unit during the Redskins' 1982 training camp.
 Bugel is known by the nickname "Boss Hog".
Matthew A. "Matt" Dyson (born August 1, 1972) is an American football coach and a former player.
 He is currently the head coach of the George Mason University football team.
 He played college football as an outside linebacker for the University of Michigan from 1991 to 1994.
 He was selected as a first-team All-Big Ten linebacker in 1992 and the defensive player of the game in the 1994 Holiday Bowl.
 He was selected by the Oakland Raiders in the fifth round of the 1995 NFL Draft and appeared in four games during the 1995 Oakland Raiders season.
