Led on the field by 26-year-old passing halfback Billy Williams, Idaho compiled a overall record. The Vandals opened the season at home with a 27–7 win over the of Tacoma, then traveled to northern California and defeated Stanford 19–16, their only win in the series, after five defeats. After a season the previous year, Stanford fielded one of its poorest teams in 1947 and went winless At the time, it was thought to be the first Idaho football win over a California school in the PCC, and 5,000 greeted the team at the Moscow train station on Monday morning; classes were cancelled and the public schools were closed.

With the excitement after the win at Stanford, the game at Neale Stadium drew an overflow attendance of 22,500, then a record gathering of any kind for the Palouse and the state of Idaho. The loss ran the winless streak against the Cougars to 21 games, a record of since taking three straight in ; the Vandals tied again in 1950 and finally broke the streak in 1954 in Pullman.

That included a humbling shutout at home to Montana for the Little Brown Stein on a Friday afternoon in November; the Grizzlies had also won with a shutout the previous year, in Missoula. The season finale the next week in Boise was an improvement, with a 13–6 upset of Utah in the rain at Public School Field to finish at. It was the first Vandal football game in Boise in five years and had a record overflow crowd; Idaho improved its record in Boise games to .
