Further complicated by the effects of the 1918 flu pandemic, the 1918 college football season was severely impacted. Kline led Nebraska through the stunted 1918 season, managing a 2–3–1 (0.417) record.
Henry Schulte (1919–20, 8–6–3, 0.559), with thirteen years as a coach at other schools before arriving at Nebraska, managed over the next two years to barely attain a winning record as the program recovered from the war and aftermath.
His winning percentage as Nebraska's 12th head coach remains an all-time program best.
When the United States became involved in World War I, many young men went off to war, depleting the ranks of football teams nationwide.
In addition, travel was severely restricted, causing the cancellation of numerous scheduled football games.
Nebraska was led by three head coaches during the war years, with a scarcity of players available as so many of the country's young men were abroad and at war.
By 1945, the year the war ended, the Cornhuskers recorded a losing 11–24–0 (0.314) record.
