The setup

Portland State led No. 6 UC Davis 21-0 at halftime and outgained it 257-84, then lost 31-24 after a 31-3 second half. The Vikings already lived an entire season’s worth of mood swings in Week 0.

What I’m watching

Portland St lost 31-24 to UC Davis in Week 0, with Tyrese Smith completing 23 of 36 for 268 yards, 0 TD and 1 INT. The Week 1 opponent changes the degree of difficulty, but 357 yards—268 passing and 89 rushing—gives us a real 2026 starting point instead of another projection.

Personnel snapshot

• What carries over for the FBS team: Portland St’s Chris Fisk is in Year 1; San Diego St’s Sean Lewis is in Year 3. San Diego St returns 10 starters—7 on offense and 3 on defense. San Diego St also kept its head coach and offensive coordinator, so its 2025 offensive habits should carry more weight in this matchup.
• The depth advantage has to show: San Diego St should have the deeper roster, but Portland St’s path is to force the new or lightly used starters into an uncomfortable first half. With 7 offensive starters back, San Diego St should be able to settle the game without exposing every new defensive piece.
• The pressure test: Tyrese Smith led Portland St’s passing in Week 0 (23 of 36 for 268 yards, 0 TD and 1 INT); Jayden Denegal returns as San Diego St’s starter (1,807 yards, 9 TD and 8 INT in 2025). The tougher first assignment belongs to Tyrese Smith: San Diego St produced 32 sacks last season.

Three quick analysis points

• The quarterback angle: Tyrese Smith produced 301 total yards in his first start: 268 passing, 33 rushing and two rushing touchdowns. San Diego State’s opener begins against a quarterback who already has a full game’s rhythm.
• The scoring trend: San Diego State allowed only 15.4 points and 293.7 yards per game last year, ranking top-six nationally in scoring defense, pass defense and red-zone defense. The catch: only two defensive starters return.
• The running-game test: Aztecs running back Lucky Sutton rushed for 1,297 yards, 13th nationally. Portland State allowed only 87 rushing yards to UC Davis, making the ground game a direct test of whether that Week 0 front is real.
