San Francisco fans turned the Caesars Superdome into a loud, road friendly venue as the 49ers beat the Saints 26-21. A predicted 55% away crowd materialized, and the Bay Area energy surged late and on defense, with Shanahan praising the traveling support. The win suggests hostile crowd dynamics can amplify road teams and foreshadow a strong Levi’s Stadium showing, a factor fantasy managers should watch for when projecting defenses and home game impact.
