From 1995-98 Erickson was the head coach of the Seattle Seahawks. During his time there he posted a 31-33 record (the same current mark as Mike Holmgren). He inherited a team that had posted the NFL's second worst record (14-34) in the three seasons prior to his arrival."We have found what we were looking for in a new coach - a leader, a motivator, a teacher - an individual with exceptional skills in coaching the game of football," 49ers general manager Terry Donahue said. "Dennis Erickson has a long history of coaching winning teams and I am confident he will succeed in San Francisco."
The Seahawks were 8-8 in Erickson's rookie season as head coach in 1995, and followed with marks of 7-9 (1996) and 8-8 in 1997 and 1998. The 1997 club produced the NFL's top rated passing offense (274.4 yards per game) while establishing franchise marks for most yards passing (4,187), completions (359), and attempts (609). It marked the first time in the franchise's 22-year history that the club paced the NFL in any of the NFL's top six offensive or defensive categories.
Erickson has been the head coach of Oregon State since 1999. During that time he compiled a 31-17 (.645) record and took the Beavers to three Bowl Games, including a 2000 Fiesta Bowl victory over Notre Dame. In 2000 he was named the National Coach of the Year after leading the Beavers to a school-record 11-1 season and No. 5 national ranking.Erickson is perhaps best known for his success at the University of Miami where he won National Championships in 1989 and 1991. His 1989 team produced a 11-1 record, and his 1991 team went undefeated, 12-0.
