AI Game Review

Raiders defied the model's 63% prediction for Roosters — a notable upset. The predicted margin of 3.3 was reasonable against the actual 2-point result. Total score prediction of 45 was close to the actual 50 — within 5 points. Raiders trailed 12–4 at half-time before staging a second-half comeback to win 24–26. A tough result for the model — all 3 picks missed on this one.
