(Some contemporaneous sources list Jackie Hunt of Marshall College as the 1949 scoring champion. Hunt scored 162 points on 27 touchdowns in 1940. The ESPN College Football Encyclopedia excludes Madden, as Marshall College was not considered a major college in 1940. Accordingly, Hunt was selected for the Little All-America team in 1940.)
