About Jack Lambert (American football)
John Harold Lambert is an American former professional football player who was a linebacker for his entire 11-year career for Pittsburgh Steelers of the National Football League (NFL). Recognized by the Pro Football Hall of Fame in 1990 as "the greatest linebacker of his era," Lambert was the starting middle linebacker on four Super Bowl-winning teams with the Steelers. He played college football for the Kent State Golden Flashes. In 2019, he was named to the NFL 100th Anniversary All-Time Team. Early on, Carson had Lambert covering tight ends and the first back out of the backfield (unique at the time for a middle linebacker), and calling defensive play changes to match what the offense would call.
