Flores is a member of the
Sid Gillman coaching tree. After stints as an assistant coach in
Buffalo and Oakland (he won a
Super Bowl XI ring as an assistant coach under
John Madden), team owner
Al Davis promoted Flores to the Raiders' head coaching post in 1979, following Madden's retirement. In 1980, Flores led the Raiders as a wild card playoff team to win the
Super Bowl XV championship over the
Philadelphia Eagles, 27–10. This was the first wild card team to win the Super Bowl and the only team to win four postseason games en route to a title, until Denver accomplished the same feat in 1997. Flores then moved with the team to
Los Angeles in 1982. In the 1983 season Flores led the Raiders to another Super Bowl (XVIII) victory over the
Washington Redskins, 38–9. He was named AFC Coach of the year by
United Press International and the Football Writers Association in 1982. Flores was the NFL's first minority head coach to win a Super Bowl, winning twice –
Super Bowl XV with the Oakland Raiders and
Super Bowl XVIII with the
Los Angeles Raiders. After a 5–10 finish to the 1987 season, Flores moved to the Raiders' front office but left after just one year. His 83 wins with the Raiders are the second-most in franchise history, behind only Madden. While he appreciated the time spent with the Raiders, Flores once stated that he believed his lack of induction in the
Pro Football Hall of Fame was because of the "dominating force" cast by Davis. On February 22, 1989,
Ken Behring (a close friend of Flores) of the
Seattle Seahawks hired Flores to serve as team president and general manager after not renewing
Mike McCormack's contract. After the 1991 season, head coach
Chuck Knox agreed to part ways after meeting with Flores and the owner. Flores had wanted
Dennis Erickson (then of the
University of Miami) to be the new head coach but Erickson elected to stay with Miami. On January 6, 1992, he appointed himself head coach of the Seahawks. In the offseason, the team elected to move on from
Dave Krieg as quarterback that left a roster of
Kelly Stouffer,
Stan Gelbaugh, and
Dan McGwire. The team went from 7–9 the previous year to 2–14, complete with scoring 140 points, the lowest total by a team for an entire 16-game season in NFL history. The one bright spot was
Cortez Kennedy, who won the
NFL Defensive Player of the Year. The Seahawks elected to go with
Rick Mirer at quarterback for 1993 that resulted in a 6–10 campaign where they lost five of their last six games. The 1994 team started 3–1 but then lost four in a row on the way to a 6–10 finish. Five days after the season ended, on December 29, 1994, the Seahawks fired Flores and his entire staff. Flores left pro football with a lifetime coaching record of 97–87 (52.7%), as well as an 8–3 playoff record, with two Super Bowl victories. ==Post-coaching career==
