The New Orleans Saints enter 0-1 after a 28-33 Week 1 loss to the Detroit Lions — the offense looks porous, no established franchise QB on the roster.

The 39.5 total suggests modest scoring without changing the expected winner. Cassandra calibration: 73% (slightly below the market line to account for single-game variance).
Arsenal most recently beat Sunderland AFC 2-0 away on September 12, 2026 – a Cassandra prediction confirmed as a hit. The Gunners are in strong early-season form in 2026/27.

Stroud are structural advantages; the Bengals travel as slight underdogs.
The Los Angeles Chargers host the Las Vegas Raiders on September 20, 2026 at SoFi Stadium (Inglewood, CA). Opening spread: Chargers -8.5 points (~73% pre-Week 1). However, the Chargers lost at home Week 1 to the Arizona Cardinals 14-26 — the line will have tightened. Nevertheless, the Chargers with QB Justin Herbert remain structural home favorites against a weak Raiders offense. Own estimate: ~60% after adjusting for the poor Week 1 result.
