I watched the game. Not sure about SF "letting them back in". It was 38-10 with just 7 minutes left. Goff played lights out in the second half including at the 7 min left mark. After Goff throws a td the onside kick bounced off the up front niner and recovered by Lions. Then another score by Lions (Goff 3 td passes). Then another onside that recovered by Niners but in an ensuing play their RB fumbles and recovered by Lions. Goff drives them down to the 25 yd line (I think) and time runs out with Lions needing only a td and 2 pt conversion to come back from 38-10 Niner lead. Quite a game-especially the last half of the 4th qtr.
