Portland State Vikings Preview
Portland State nearly pulled off a major upset against UC Davis after building a 21-0 first-half lead. Tyrese Smith completed 23 of 36 passes for 268 yards with one interception and also rushed for two touchdowns. Devon Anderson caught six passes for 99 yards, while Cru Newman had seven receptions for 66 yards and added a 78-yard punt-return touchdown. The Vikings struggled on the ground outside of Smith, finishing with only 89 rushing yards on 37 attempts.
The Portland State defense kept UC Davis scoreless in the first half before allowing 31 points after the break. The Vikings gave up 374 total yards, including 287 through the air, but Eddie Vega recorded an interception. Avery Ducsik produced Portland State's only sack. The Vikings now face an Aztecs offense built around a strong rushing attack, making Portland State's ability to hold up against repeated carries a major part of this matchup.
San Diego State Aztecs Preview
San Diego State brings back a deep backfield after rushing became the foundation of the offense last season. Lucky Sutton returns after running for nearly 1,300 yards and 10 touchdowns, while Christian Washington gives the Aztecs another proven option. The two combined for close to 1,900 rushing yards and 14 scores. Quarterback Jayden Denegal also returns, along with leading receiver Jordan Napier and deep threat Donovan Brown. San Diego State ran at least 40 times in 11 games last season and won nine of them.

The defense requires more rebuilding after ranking 11th nationally in total defense and sixth in scoring defense last season. Twelve of the top 14 tacklers are gone, including several major pass rushers. Dalesean Staley returns after recording 81 tackles and 10 pass breakups, while transfers Gavrien Lightfoot, Djibril Rahman and Kai Wallin help rebuild the front. The Aztecs also added 330-pound defensive tackle Tuaoa Tauili'ili directly from Portland State.
Portland State Vikings vs San Diego State Aztecs Prediction
Portland State showed it can create explosive plays against UC Davis, but the Vikings also scored only three points after halftime and averaged 2.4 yards per rush. That makes this a difficult matchup against an Aztecs team that can control possession with Sutton and Washington. The 40.5-point spread requires San Diego State to keep producing after the game is under control. The Aztecs have enough returning offensive talent to do that, while Portland State's second-half problems against UC Davis raise concerns about the Vikings handling four quarters against a deeper roster. San Diego State's ground game will set up a comfortable home opener, and the defense will limit Portland State's scoring chances. Final Score Prediction: San Diego State Aztecs win and cover ATS, 49-7.
