PALO ALTO — Bobb McKittrick, the San Francisco 49ers' gritty offensive line coach who worked with five Super Bowl-winning teams in 21 years, died Wednesday of cancer. He was 64.
McKittrick was diagnosed with bile duct cancer in January 1999 and died at Stanford University Medical Center.
The former Marine Corps officer was known for taking his military training onto the field, instilling the virtues of hard work and dedication in his players. He favored shorts and T-shirts on the sidelines during practice, no matter the temperature.
"Bobb McKittrick has been universally acclaimed as one of the great coaches of our time," 49er General Manager Bill Walsh said. "He was the most successful offensive line coach the game has ever seen. His spirit and standard of excellence will always be a part of the 49ers' tradition."
McKittrick's on-field coaching duties were assumed by Pat Morris last season, but McKittrick stayed involved with the 49ers despite undergoing surgery and chemotherapy.
