PULLMAN — When Washington State takes the field this weekend against No. 21 Boise State, the Cougars will be in for a lot of firsts.

It’ll be WSU’s first time hosting Boise State since 2017, when the late Tyler Hilinski came off the bench to lead a wild comeback. It’ll be the first time that Cougar coach Kirby Moore has faced the Broncos, for whom he played in the early 2010s. It will also be quarterback Owen Eshelman’s first home start after taking over the reins last weekend.

But what about the previous matchups between the Cougs and Broncos, who will be meeting for the first time as Pac-12 foes? The teams have only clashed seven times before. WSU owns a 5-2 record in the matchup.

Here is a look back at all seven games, in chronological order:
