AI Game Review

Panthers defied the model's 53% prediction for Broncos, a notable result. The margin model missed here, predicting 3.0 but the actual margin was 24 points. Total score prediction of 44 was close to the actual 40, within 4 points. Panthers led 20–8 at the break and pulled away in the second half to win by 24. The model went 1/3 on this match. The under 47.5 total call was correct.
