LeBeau finished his 14-year career in 1972 with 62 interceptions, still eighth in NFL history. He led the league in picks in 1970 with nine.
Elected by the senior committee after a 32-year wait, LeBeau joins Dick "Night Train" Lane and Yale Lary, who played in the same secondary, in the hall.
The 73-year-old LeBeau, the oldest coordinator in the league, admits he's best known as an assistant coach, the mastermind of the zone blitz. His Pittsburgh Steelers won Super Bowls in 2006 and 2009.
The Steelers bused in from training camp to watch his induction Saturday. LeBeau singled out their presence at Fawcett Stadium as "just about the highest compliment ever paid to me in my life."
