Lott switched to the safety position in 1985. He had the end of his left pinky finger removed after the 1985 season because it was crushed while playing. A 1986 injury made him not play that season's last two games. He still had 10 interceptions. This was the most in the league and his personal best. In his 10 years with the 49ers, Lott helped them win four Super Bowls: XVI (1981), XIX (1984), XXIII (1988), and XXIV (1989).
