AI Game Review

Dolphins defied the model's 66% prediction for Sharks, a notable upset. The margin model missed here, predicting 6.0 but the actual margin was 28 points. Total score prediction of 47 was close to the actual 48, within 1 points. Dolphins led 4–16 at the break and pulled away in the second half to win by 28. The model went 2/4 on this match. The 1-12 margin band call landed. The under 55.5 total call was correct.
