What really happened

Final: Chargers 23, Ravens 17. Chargers won 23-17 — the drive turned it over.

Playoff football. Chargers ball, up 6 — a field goal pushes them to a touchdown. At their own 22, 1:56 on the clock.

nflverse's historical win-probability estimate for this exact situation was 96.8% for Chargers. Our model starts at 93.2%. The two numbers are estimates, not verdicts — the gap between them is a reminder that endgame win probability is hard to pin down.
