Win Probability

AI Game Review

Broncos defied the model's 58% prediction for Storm, a notable result. The margin model missed here, predicting 4.0 but the actual margin was 16 points. Total score prediction of 45 was close to the actual 44, within 1 points. Broncos led 12–4 at the break and pulled away in the second half to win by 16. The model went 1/3 on this match. The under 48.5 total call was correct.
