Boise State vs. Washington State: Can the Cougars slow the Broncos’ ground game?

Boise State’s running game gives Washington State a difficult problem, but the Cougars haven’t been as easy to beat at the betting window as their 1-6 record suggests. The No. 21 Broncos arrive as 13.5-point favorites, making Saturday’s matchup about more than which team is stronger: can Washington State generate enough offense to keep Boise State from taking control on the ground?

Boise State has more than one way to move the ball

The Broncos beat Fresno State 38-31 in their last game, with Dylan Riley rushing for 150 yards and Sire Gaines adding 120. Riley also scored on a 44-yard reception, while Maddux Madsen threw for 238 yards and two touchdowns. That combination made it difficult for Fresno State to get off the field: Boise State piled up 512 yards and held the ball for 38:58.

Our projections point toward another substantial rushing workload, with about 42 carries and 190 rushing yards for the Broncos, alongside 220 passing yards. That’s a balanced production outlook rather than a repeat of the huge rushing performance at Fresno State. For Washington State, the challenge is to interrupt those drives before Boise State can keep stacking first downs.

There’s a useful distinction between winning and covering here. Boise State has won five straight, but its last two victories—38-31 over Fresno State and 37-18 over Utah State—both fell short of the spread.

Washington State’s record leaves out part of the story

The Cougars have covered in five of seven games this season. Flat one-unit bets on Washington State against the spread would have returned a historical profit of 2.72 units. That doesn’t settle this week’s price, but it helps explain why the six losses alone aren’t enough to assess a double-digit handicap.

Last Saturday provided a good example. Washington State lost 48-30 at Oregon State but covered the 18.5-point spread. In his first career start, Owen Eshelman threw for 289 yards and two touchdowns and ran for 136 yards and another score. The catch is the timing: the Cougars trailed 27-10 at halftime before putting together three straight touchdown drives late.

That performance gives Washington State something to build on, although our projections are more restrained for this matchup: about 175 passing yards and 130 rushing yards. The Cougars’ best case for staying close is turning last week’s late production into offense earlier in the game, rather than asking for another comeback after falling well behind.

What that means for the 51.5-point total

Boise State’s production and Washington State’s latest offensive spark give the scoring outlook some life. Five of the Broncos’ six games this season have gone over their totals. But Washington State has gone under in four of seven, and its 30 points at Oregon State followed games of six and 16 points.

At 51.5, the important tension is between Boise State’s ability to sustain drives and Washington State’s ability to contribute consistently. Long rushing possessions could limit the Cougars’ opportunities, while another productive passing-and-running performance like Eshelman’s last outing would make the scoring environment look quite different. Washington State’s uneven output is the biggest uncertainty.

The matchup hinges on an earlier response

Boise State has the clearer foundation: productive backs, a passing game that contributed against Fresno State and a projected workload that keeps the ground game central. Washington State’s counterweight is its record against sizable spreads, now paired with an encouraging—but late-arriving—offensive performance. Sustaining drives early would give the Cougars a way to keep pace rather than chase another large deficit. That’s the most useful test of whether last week’s offensive spark changes this matchup, both against the spread and at the posted total.
