Win probability is nflverse's model, which starts from the betting line and updates before every snap with the score, the clock, down, distance, field position and timeouts. A swing is the change in one team's chance across a play, in percentage points. Each play is tagged with the team that had the ball; the bar names the team it helped. The turning point is the play after which the winner never fell to 50% again.
