Idaho’s schedule in 1929 was again flush with regional foes. The Vandals opened the season with two warm up games against regional competition. They bested the Bobcats of Montana State and whipped Whitman College in Moscow. Idaho’s media guide lists this game as an away game, but the newspapers show it to have taken place in Moscow. Two other regional opponents rounded out the Vandal non-conference schedule. Idaho again lost to Gonzaga and again beat Idaho State. In typical Idaho fashion, the Vandals went 3-1 in out of conference play and 1-4 in PCC competition. The only conference victory was against Montana.
The annual game with WSU turned out to be a lopsided affair. However, its 41-7 score is misleading. Idaho held its own with WSU through three quarters only to give up four touchdowns in the fourth quarter.
1929 was also the first year of the Leo Calland era of Vandal football. He came to Moscow from USC. His appointment marked a change in Idaho athletics. He was not only the football coach but head of the department of physical education and athletics. This was seen as a positive thing aimed at reducing friction between the athletic and academic sides of the house.
Calland’s former employer, the USC Trojans, thoroughly outclassed Idaho 72-0 in Los Angeles. The Vandals never gave up, though, as they marched down to the USC five yard line in the fourth quarter only to lose the ball on downs.
In 1929 the Idaho Vandals made a change to the program which has reverberated for decades. The Vandals played in red uniforms. In an attempt to draw on the previous success of the 1923-1925 years, Idaho went back to red uniforms. Occasionally the red uniforms would make further appearances, most notably in 1948 during homecoming. This occasional jersey has led to much rumor and investigation into its origins. However, it appears that red uniforms were a traditional Vandal color.
