Most likely exact margins: KC by 3 (8.4%), LV by 3 (8.2%) and KC by 7 (5.1%). NFL scores come in 3s and 7s, so margins of 3, 7, 10 and 14 come up far more often than their neighbours.

On this curve Kansas City Chiefs were 36.6% to cover the line (KC −4.5): to win by more than 4.5.

The curve is a normal spread of results around the model’s expected margin (Stern, 1991), reweighted for the NFL’s key numbers. Its shape was fitted on 2002–2023 and checked on 2024, where it beat a plain bell curve. Because it is built from the expected margin alone, its win chances can differ by a few points from the Elo figure above, which is the one the Model Lab scores.
