In his day, John Mackey revolutionized the tight end position. To most, the tight end was basically just another tackle on the line, but Mackey was able to use his speed to add another dimension to his game and be a legitimate downfield receiving threat. He played for the Baltimore Colts for nine seasons before finishing his 10-year career with the Chargers in 1972. Mackey only missed one game in 10 years before leg and knee injuries caused his playing days to come to an end. As a rookie, he started every game and became the only first-year starter to be selected for that season’s Pro Bowl. His legacy is perpetuated through the “John Mackey Award,” which was established in 2001 and is annually given to the most outstanding tight end in Division I-A college football.
