Seifert is a San Francisco native: he was an usher at Kezar Stadium in 1957 as a high school senior at Polytechnic, across the street from Kezar, and watched the 49ers lose in the playoffs that year, 31-27 to the Detroit Lions. Lynn Stiles, another former 49ers assistant coach, said: “It’s damn near a love affair George has with the 49ers. It goes way beyond working for a living.”
One day, Seifert looked out at Marina Boulevard and remembered: “My uncle owned a company that washed windows, and when I was in high school and college I’d work for him to make my extra money. I used to wash some of these windows right here on this street. It’s really funny because I’m afraid of heights, and the work scared the crap out of me. I remember times when I’d freeze on the platform.”
Seifert had a 108-35 record, for a .755 winning percentage, when he left the 49ers after 1996. His routines were legendary: he never walked on the 49ers helmet spray-painted on the turf of the team practice fields, he blew on each Certs he ate three times upon putting it in his mouth, and he did a shirtless lap around the 49er locker room before each game.
