Leon Green played defensive end at Idaho from 1934-36 before defensive statistics were recorded. Green captained the team each of his final two seasons.
In 1935, the Vandals boasted a stout defense – never allowing more than 14 points in a game – and Green earned Associated Press All-America honors. After serving in World War II, he returned to work at the University of Idaho where, in 1951, he became Professor and head of the Physical Education Department, a position he held until his retirement in 1978. Green also served as athletic director from 1973-78, where he raised money and directed the construction of the Kibbie Dome.
