Larry Richard Csonka is an American former professional football fullback in the National Football League (NFL) for the Miami Dolphins for the majority of his career, along with the New York Giants for three years. He also had a short stint with the Memphis Southmen in the WFL. Nicknamed "Zonk", Csonka is widely regarded as one of the greatest running backs of all time. Csonka is mostly remembered for his success during his tenure with the Dolphins, which included being a member of their 17–0 perfect season in 1972, and winning Super Bowl championships in 1972 and 1973, the latter of which he was named Super Bowl MVP when he ran for a then-record 145 yards. He was also a commentator for the original run of American Gladiators.

The 1972 Miami Dolphins season was the franchise's seventh season and third in the National Football League (NFL). The team was led by third-year head coach Don Shula and achieved the only perfect season in NFL history. They also led the league in both points scored and fewest points allowed.
