1917 Idaho football team

The 1917 Idaho football team represented the University of Idaho in the 1917 college football season. Idaho was led by second-year head coach Wilfred C. Bleamaster and played as an independent; they joined the Pacific Coast Conference five years later in 1922. Idaho had two home games in Moscow on campus at MacLean Field, with none in Boise.

Idaho dropped a fourth consecutive shutout to Washington State in the Battle of the Palouse, falling 0–19 at home. Six years later, the Vandals won the first of three consecutive, their only three-peat in the rivalry series.

Idaho opened with three losses, then won twice for a 2–3 record; they did not play Gonzaga this season.

1918
The following year in 1918, Idaho's football team was non-varsity, composed of Student Army Training Corps (SATC) players. After the Armistice ending World War I, they played a limited schedule and defeated Washington State's SATC team 7–6 in Moscow in December.

Idaho's first two games were against Gonzaga; the opener in Moscow on November 16 was a 13–7 Idaho win, and they tied the next week in Spokane at seven points each. Idaho played another in Spokane on November 30, a 0–68 loss to a team of U.S. Marines from Mare Island Naval Shipyard in California.
