NFL Hall of Fame member John Mackey is considered to be the best to have played the tight end position. A tight end by whom all others are measured, Mackey was a role model on and off the field as demonstrated by his Super Bowl Championship, his commitment to community and his place in history as the first President of the NFLPA.
