Montana and Walsh have both been inducted into the Pro Football Hall of Fame. Several members of Bill Walsh's coaching tree went on to successfully implement his West Coast Offense system. George Seifert succeeded Walsh as San Francisco's head coach in 1989, and won two Super Bowls with the 49ers; once with Joe Montana at quarterback in 1989, and later with fellow Hall of Famer Steve Young in 1994. Paul Hackett was another former assistant coach who once served under Walsh. He served as a 49ers assistant from 1983-1985, coaching quarterbacks & wide receivers. During this time, Hackett helped San Francisco win Super Bowl XIX. He next served as offensive coordinator for the Dallas Cowboys under Tom Landry from 1986-1988. Hackett would later teach his version of Walsh's offense to several coaches, including former Green Bay Packers head coach Mike McCarthy. McCarthy, who was the Packers head coach from 2006 until December 2018, would go on to win a Super Bowl himself with the use of the West Coast offense in 2010, with the help of superstar quarterback Aaron Rodgers. Mike Holmgren is another prominent member of Bill Walsh's coaching tree. When Holmgren first came to San Francisco as an assistant coach, he started as Walsh's quarterbacks coach from 1986-1988. Holmgren then served as offensive coordinator for the 49ers under Seifert from 1989-1991. From 1992-1998, Holmgren was the head coach of the Green Bay Packers. He won a Super Bowl with the Packers in 1996 behind the quarterbacking of 3-time NFL MVP Brett Favre. He then returned to the Super Bowl in 1997, but the Packers lost to the Denver Broncos, who were coached by Mike Shanahan. Holmgren later became head coach of the Seattle Seahawks, leading them from 1999-2008. They played in Super Bowl XL after the 2005 season. The Seahawks, however, lost to the Pittsburgh Steelers. Holmgren is credited for helping mold successful quarterbacks such as Montana, Young, Favre and Matt Hasselbeck. As a head coach, he compiled an overall 174-122 record in the NFL: 161-111 in the regular season, along with a 13-11 playoff record, 3 Super Bowl appearances and 1 Super Bowl title. One of Holmgren's former assistants, Jon Gruden, has had reasonable success running the West Coast offense in his own right. He started his head coaching career with the Oakland Raiders, leading them from 1998-2001, and turned the Raiders into a strong playoff contender.
