Richard Smith was named the Dolphins’ defensive coordinator by Head Coach Nick Saban on March 2, 2005. Smith comes to the Dolphins with 17 years of NFL coaching experience on his résumé, including the last two with the Detroit Lions, when he served as that team’s assistant head coach/linebackers.

Before joining the Lions in 2003, Smith spent six seasons (1997-02) with the San Francisco 49ers, where he coached the team’s linebackers. During that time, four of his linebackers were selected for the Pro Bowl; Julian Peterson in 2002, Winfred Tubbs in 1998 and both Ken Norton, Jr. and Lee Woodall in 1997.
Prior to his stint in San Francisco, Smith spent four seasons (1993-96) with the Denver Broncos coaching special teams, while also assisting with the linebackers for three seasons (1993-95).
Smith began his NFL coaching career with the Houston Oilers in 1988 where he coached special teams and assisted with the tight ends (1988-89), linebackers (1990-91) and the offensive line (1992). The Oilers qualified for the postseason in each of Smith’s five seasons with the club. In fact, the teams with which Smith has been a part of in the NFL have reached the playoffs in 11 of his 17 seasons, including four appearances with San Francisco (1997-98 and 2001-02), two with Denver (1993, 1996) and five with Houston (1988-92).
In 1987, Smith spent a season at the University of Arizona coaching linebackers and special teams after tutoring the outside linebackers and special teams from 1984-86 at the University of California.
