1978 Topps football card of Hall of Fame fullback Larry Csonka, one of the hardest-running backs of all time. His most successful seasons came in the first seven years of his career in Miami, where he was a five-time Pro Bowler and key cog in a pair of Dolphin Super Bowl titles. Looking for a bigger paycheck in a non-free agency era of the NFL, Csonka jumped to the Memphis Southmen of the new World Football League in 1975 (along with teammates Jim Kiick and Paul Warfield), but lasted only one season there. He returned to the NFL the following year, signing with the New York Giants and playing there for three uneventful seasons. He returned to Miami for a year and had a decent season, but when the Dolphins failed to give him a new contract he retired.
