How The Model Sees It

Our rating has San Francisco 49ers as the stronger side by 252 rating points, which on its own is worth about 10.1 points on the scoreboard (SF 1,635, LAC 1,383).

Home field adds 1.4 points to LAC — a measured figure from our backtest, not the traditional three, because home advantage in the modern NFL is considerably smaller than it used to be.

That lands on a projected margin of -8.7, and running that through the historical spread of actual results against projections gives San Francisco 49ers at 75%.

No betting line has been posted for this game yet — books typically price about three weeks ahead. Until one appears, this page shows the engine's number with nothing to compare it against, which is exactly the situation the model is most useful in.
