A. Tittle, Bob St. Clair and Hugh McElhenny. <P1-S4>  In terms of tenure, Bill Walsh has coached more games (152) and more complete seasons (10) than any other head coach in 49ers franchise history. <P1-S5>  He led the 49ers to playoff appearances in seven seasons, three of which led to the Super Bowl championship, in 1981, 1984 and 1988. <P1-S6>  Jerry Rice, Joe Montana, Charles Haley, Ronnie Lott, Johnny Davis, Roger Craig, Fred Dean and Steve Young are among the players Walsh has coached in his career. <SEP> <P2-S0> Steven Daniel Hendrickson (born August 30, 1966) is a former professional American football linebacker in the National Football League. <P2-S1>  Hendrickson attended Napa High School where he was an outstanding varsity player during all four years at the school. <P2-S2>  His #30 jersey remains the only one ever retired by the school. <P2-S3>  He played college football for the California Golden Bears at California where he graduated with a major in history. <P2-S4>  He was named defensive player of the game at the 1988 Blue-Gray Football Classic and was drafted in the sixth round of the 1989 NFL Draft by the San Francisco 49ers. <P2-S5>  He played seven NFL seasons for the San Francisco 49ers, Dallas Cowboys, San Diego Chargers, Houston Oilers and Philadelphia Eagles. <P2-S6>  Hendrickson was a member of the San Francisco 49ers when they won their fourth Super Bowl XXIV on January 28, 1990. <P2-S7>  During his professional career, he played various positions despite his relatively small stature. <P2-S8>  Hendrickson is fondly remembered among Chargers fans for being used as a short yardage, goal line running back, despite the fact that his main position was a defensive one. <P2-S9>  In particular, Hendrickson scored on a 1-yard run against the Kansas City Chiefs in a January 1993 playoff game in San Diego, to cap off a 17-0 shutout of the Chiefs. <SEP> <P3-S0> William Ernest Walsh (November 30, 1931 – July 30, 2007) was an American football coach. <P3-S1>  He served as head coach of the San Francisco 49ers and the Stanford Cardinal football team, during which time he popularized the West Coast offense. <P3-S2>  After retiring from the 49ers, Walsh worked as a sports broadcaster for several years and then returned as head coach at Stanford for three seasons.
