What really happened

Final: 49ers 20, Broncos 14. 49ers won 20-14 — the drive turned it over on downs.

49ers ball, up 6 — a field goal pushes them to a touchdown. At their own 20, 3:51 on the clock.

nflverse's historical win-probability estimate for this exact situation was 88.2% for 49ers. Our model starts at 88.3%. The two numbers are estimates, not verdicts — the gap between them is a reminder that endgame win probability is hard to pin down.

This is our own model estimate, not the real coach's grade and not a claim about what the “correct” call was. Football decisions depend on the opponent, personnel and game plan — the model only measures how a call changes win probability in this situation.
