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. The turning point is the play after which the winner never fell to 50% again.
J.Smith-Njigba led the Seahawks at +5.9 EPA (6 catches for 84). D.Robinson led the 49ers at +1.4 EPA (3 catches for 24).
