Question: Which position did this head coach of 2017 Oakland Raiders sessions play in the 1980s?

<P0-S0>  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. <P0-S1>  The Raiders began the season on September 10 at the Tennessee Titans and will finish the season December 31 at the Los Angeles Chargers. <P0-S2> 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. <P0-S3>  The Raiders, as they did in 2016, will play one home game in Mexico City, this time against the New England Patriots. <SEP> <P1-S0> There have been 20 head coaches for the Oakland Raiders of the National Football League (NFL). <P1-S1>  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. <P1-S2>  The Raiders joined the NFL in 1970, after the AFL–NFL merger. <P1-S3>  They played in Los Angeles between 1982 and 1995, before returning to Oakland. <P1-S4>  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. <P1-S5>  In those games, two coaches have won the Super Bowl with the team: John Madden in 1976 and Tom Flores in 1980 and 1983. <P1-S6>  One coach, John Rauch in 1966, won the AFL Championship. <P1-S7>  Three other coaches, Art Shell, Jon Gruden and Bill Callahan, have also taken the Raiders to the playoffs. <P1-S8>  Callahan led the Raiders to the Super Bowl. <P1-S9>  He did this in his first year as head coach of the team. <SEP> <P2-S0> Jack Louis Del Rio Jr. (born April 4, 1963) is head coach of the Oakland Raiders of the National Football League (NFL). <P2-S1>  A linebacker for four NFL teams between 1985–1996, he played both football and baseball for the University of Southern California Trojans. <SEP> <P3-S0> 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. <P3-S1>  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. <P3-S2>  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. <P3-S3>  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. <P3-S4>  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.
