The Vandals opened the 1925 campaign against in-state competition in the form of the College of Idaho Coyotes. The Coyotes put up quite a fight, exposing the weak Vandal pass defense. The 16-14 victory over the supposedly far inferior Coyotes gave the Vandals little hope of success in the upcoming conference slate.
Successful or not, fan excitement was already building for the season. The one and only time that USC would ever visit Moscow would occur in 1925 and fans were excited. Special trains were being arranged from Boise for a four-day stay in Moscow.
A week after the squeaker against the C of I, the Vandals surprised many fans by upsetting Oregon in Eugene. Idaho came into the game a slight underdog, but held the Ducks scoreless, winning 6-0. The victory made it two in a row over the Ducks – Idaho’s longest streak against Oregon to date. The victory also marked 3 games in a row without a loss to Oregon. The streak would be lengthened to 4 in a row without a loss in 1927. This four game/five year stretch against Oregon may indicate the all time high water mark for Vandal football. The Vandals were a very good team in the mid 1920’s.
The next week, Idaho defeated Washington State for the third time in a row. As always, the game was not short on controversy. Idaho scored its touchdown on a WSC fumble which was returned for a score. WSC fans and players claim the play was blown dead, but the referees allowed the score. To secure the 7-6 victory, Idaho blocked a would-be game winning field goal attempt by WSC in the closing minutes. The defense of both squads played a great game. Idaho didn’t complete a pass but the defense limited the Cougars to two field goals.
Unfortunately the 3-0 record would be the high water mark for Idaho’s season. The Mighty Vandals would go on to lose the next five in a row, finishing 3-5. The first of those five losses would come against the Bulldogs of Gonzaga. Idaho held the Bulldogs scoreless in the second half, but could only muster three points for the game, unable to overcome Gonzaga’s early fireworks.
Idaho’s offensive struggles continued against USC in Moscow. The Trojans scored at-will against the Vandals, winning 51-7. USC’s sensational quarterback lead the team to eight first-half first downs while Idaho could only muster three. It was a long day for the Idaho defense giving up touchdown after touchdown to a much better USC team.
In the annual Boise game, the Vandals clashed with the Aggies of Oregon State. The game was expected to be close and indeed it was, with the Aggies coming out on the right end of a 16-7 victory.
Idaho finished the season with a 2-3 conference record and it figures the dreaded Griz kept Idaho from a winning record in-conference. The Vandals wrapped up the season with a peculiar intersectional game against the Creighton Jays. The game was a Thanksgiving affair played in Omaha. The Argonaut reports that one Idaho player had to be carried off the field after breaking an ankle in two places.
