What is who is the oldest heisman trophy winner?

The oldest Heisman Trophy winner was Johnny Rodgers, who won the award in 1972 at the age of 22 while playing for the University of Nebraska. He later played professionally in the Canadian Football League. However, Rodger's age at the time of receiving the Heisman Trophy is not particularly significant as the award is typically given to college football players relatively early in their playing careers.
