Joiner finished his 18 AFL/NFL seasons with 750 receptions for 12,146 yards (16.2 average per catch) and 65 touchdowns. He retired as the then-NFL leader in career receptions, yards, and games played by a wide receiver. At age 39, Joiner also retired as the oldest wide receiver in NFL history (since surpassed by Jerry Rice among others). Joiner credited his success and longevity to Coryell: "Thanks to Coach Coryell’s offense and his revolutionary passing game, he prolonged my career, from the day I got to the Chargers until the day I retired. I will forever be grateful to him and what he did for the game of football.” Joiner was inducted into the Pro Football Hall of Fame in 1996.
