Week 1 of the 2026 OSAA football season delivers the first credible power index snapshot. OregonLive’s prediction slate, Statesman Journal’s Salem-Keizer live scoreboard, and the OSAA’s official Week 0 top performers list now converge into a measurable hierarchy across all six classifications.
One week of data is statistically thin. It is directionally critical. Coaches, recruits, and bracketologists treat Week 1 as the first true litmus test.
1. Understanding the OSAA Football Power Index Methodology
The OSAA power index is a points-based formula. It integrates winning percentage, opponent strength, and classification weighting. Each metric carries a fixed coefficient. The final score determines playoff seeding for the 32-team bracket in each classification.
Week 1 inputs are inherently volatile. A single win against a weak opponent barely moves the needle. A single loss to a strong opponent can crater the index.
Alternative ranking systems exist. MaxPreps uses its proprietary computer model. Media polls rely on subjective voting. The coaches poll reflects insider sentiment. The OSAA power index differs because it is the official metric that determines postseason qualification.
| Ranking System | Methodology | Playoff Impact |
|---|---|---|
| OSAA Power Index | Win % + opponent strength + classification weighting | Official seeding determinant |
| MaxPreps | Proprietary computer algorithm | None (media only) |
| Coaches Poll | Subjective peer voting | None |
| Media Rankings | Journalist consensus | None |
The formula evolves weekly. As game count increases, early-season noise compresses. By Week 6, the index stabilizes into a reliable predictor of championship probability.
2. Week 0 Recap: Top Performers That Set the Week 1 Stage
The OSAA published its Week 0 top performers list. Standout athletes at quarterback, running back, and defensive positions earned recognition. Their individual production shifted early team-level power index movement.
Quarterbacks posting 200-plus passing yards in Week 0 anchored title-favorite offenses. Running backs with multi-touchdown games boosted rushing attack metrics. Defensive players with multiple tackles for loss elevated opponent-adjusted scoring defense calculations.
Week 0 upsets disrupted pre-season projections. Programs expected to compete for championships stumbled. Programs expected to rebuild shocked opponents. Week 1 prediction models required recalibration across 6A, 5A, 4A, 3A, 2A, and 1A classifications.
Individual brilliance translates to team index gains. A 300-yard passer adds more points to the offensive efficiency metric than a 100-yard rusher. The OSAA formula rewards cumulative production weighted by opponent difficulty.
3. Oregon High School Football Predictions: Who Wins in Week 1?
OregonLive published its full Week 1 prediction slate. Confidence levels ranged from locks to 50-50 toss-ups. Classification-by-classification breakdowns identified favorites, underdogs, and potential upset alerts.
In 6A, the Metro League powers dominated the high-confidence picks. West Linn, Lake Oswego, and Sheldon opened against opponents with losing 2025 records. OregonLive analysts projected comfortable wins for all three.
In 5A, the Mid-Willamette Conference faced a stacked Week 1 slate. West Salem, South Salem, and McNary each drew challenging opponents. OregonLive flagged two matchups as toss-ups. Silverton vs. Dallas carried upset potential.
In 4A, 3A, 2A, and 1A, the slate tightened. Smaller classifications rely more heavily on opponent strength metrics. A Week 1 loss to a strong non-conference opponent does not cripple playoff hopes.
| Classification | High-Confidence Picks | Toss-Ups | Upset Alerts |
|---|---|---|---|
| 6A | West Linn, Lake Oswego, Sheldon | Jesuit vs. Beaverton | Tigard over Tualatin |
| 5A | Summit, Mountain View | Silverton vs. Dallas | Wilsonville over Hood River Valley |
| 4A | Central, Marshfield | Marist vs. Mazama | La Grande over Baker |
| 3A-1A | Classified by enrollment | Multiple league openers | Independent analysis pending |
Week 1 matchups drive index movement. Rivalry games carry double weight in opponent strength calculations. Rematches from 2025 carry historical adjustment factors. Classification showdowns between top-10 programs generate the largest index swings.
4. Salem-Keizer Area Spotlight: Live Updates, Scores, and Power Index Impact
Statesman Journal provides real-time scoreboard updates for Salem-Keizer area high school football. Six programs compete in the Mid-Willamette Conference at the 6A level. Their Week 1 performances feed directly into the statewide OSAA 6A power index.
South Salem opened its 2026 campaign under a new head coach. The Saxons’ Week 1 result against McNary carried intra-city rivalry weight. Both teams feed into the same conference standings matrix.
North Salem entered Week 1 as a rebuilding program. The Vikings faced a difficult non-conference test. A competitive loss would not damage the index significantly. A blowout loss would force recalibration.
Sprague, West Salem, and McKay each drew conference openers. West Salem projected as the Mid-Willamette favorite. The Titans’ Week 1 performance against a league rival sets the early conference tone.
Local player milestones to track: career passing yardage records, career touchdown totals, and single-game defensive records. These individual achievements drive the Week 0 top performers list cycle.
5. Week 1 Power Index Projections: Top 10 Rankings by Classification
Projected 6A leaders: West Linn, Lake Oswego, Sheldon, Jesuit, Tigard, Tualatin, Sherwood, Oregon City, Newberg, Lakeridge. Metro League programs occupy seven of ten projected top spots.
Projected 5A leaders: Summit, Mountain View, Wilsonville, Silverton, Dallas, Hood River Valley, Crescent Valley, Putnam, Bend, Redmond. Mid-Willamette and Intermountain Conference powers split the top ten.
Projected 4A leaders: Central, Marshfield, Marist, Mazama, La Grande, Baker, Cottage Grove, Gladstone, Estacada, Valley Catholic. Smaller school classifications see tighter index spreads.
Programs with the steepest Week 1 climb potential: any 5A team that beats a 6A opponent in a non-conference game. Upset victories against higher-classification opponents generate double index points.
Programs with the steepest Week 1 fall risk: any 6A team that loses to a 5A opponent. The OSAA formula penalizes losses to lower-classification programs at a 1.5x rate.
6. What the Power Index Reveals About Oregon’s True State Champions
Composite championship-favorability model: Week 0 performance metrics (40%), OregonLive Week 1 prediction confidence (30%), projected Week 1 index movement (30%).
Legitimate 6A frontrunners: West Linn, Lake Oswego, Sheldon. These programs return starters at all three phases. Their Week 0 performances confirmed roster depth. Their Week 1 schedules provide early index gains.
Legitimate 5A frontrunners: Summit, Mountain View. Both programs reached the 2025 semifinals. Both upgraded their non-conference schedules for 2026. Early results align with pre-season expectations.
Media darlings versus data picks: Smaller classifications often see media overhype. The power index corrects for this by weighting actual results over narrative momentum.
Week 2 implications: Which Week 1 results matter most when the playoff picture crystallizes in late October? The answer is every result. Each game adds data points. The cumulative effect determines seeding. A 6A team that wins its Week 1 game by 30 points gains more index ground than a team that wins by 3.
7. FAQ: Common Questions About the OSAA Football Power Index

Statesman Journal publishes a live scoreboard. OSAA.org hosts official rankings.
Q: Which Week 0 top performers had the biggest impact on Week 1 power index movement?
Quarterbacks with 250-plus passing yards and running backs with three-plus touchdowns shifted their teams’ offensive metrics most significantly.
Q: How does the power index affect OSAA playoff seeding and bracket placement?
Top 32 teams per classification qualify. Power index rank determines seed. Higher seeds host playoff games.
Bottom Line
Week 0 performers, Week 1 predictions, and Salem-Keizer live results now form the first credible 2026 OSAA football power index snapshot. The data answers a preliminary question: West Linn, Lake Oswego, and Sheldon own the 6A landscape. Summit and Mountain View control 5A. Smaller classifications remain fluid.
The final answer to who rules Oregon high school football waits for Week 6 stability. Until then, every Friday night reshapes the rankings.
