Playoff football. Steelers ball, up 2 — every first down is a dagger. Backed up at their own 5, 2:38 on the clock.

nflverse's historical win-probability estimate for this exact situation was 71.3% for Steelers. Our model starts at 71.8%. The two numbers are estimates, not verdicts — the gap between them is a reminder that endgame win probability is hard to pin down.
