34. 42. 49ers-Lions final. 31. 50. Final

The San Francisco 49ers are headed to the Super Bowl despite being down by 17 points at halftime. It felt bleak when the Niners left the field at the half, as the Detroit Lions had dropped 24 points on them while only allowing San Francisco to put up seven points.

The Niners had fallen behind to the Packers last week but managed to come from behind and knock off Green Bay. Now they were in a similar spot but thankfully for them, Dan Campbell decided to be aggressive and go for it on fourth down rather than taking the points. This is when the momentum started to flip.

Breaking down the turning point in 49ers' win vs. Lions

At that point in the game, the Niners had tacked a field goal on to start the half, making it 24-10 in favor of Detroit. The Lions moved the ball to the Niners' 28-yard line and it was 4th-and-2. Campbell had been aggressive all season and it typically paid off for them but not in this situation. They didn't convert and the Niners then moved the length of the field and scored a touchdown in five plays.

This was helped, of course, by Brandon Aiyuk's circus catch that set San Francisco up on the Lions' 4-yard line. Three plays later, it was a seven-point game just like that.

On the Lions' first play after the Niners closed the gap, Jahmyr Gibbs fumbled the football and Tashaun Gipson recovered, giving San Francisco the ball right back. The 49ers went on to score four plays later and tied the game at 24 all.

This all was jumpstarted by Campbell and the Lions going for it and not getting the conversion. Had they kicked the field goal there, it'd have been 27-10 and that would have made it much trickier for the 49ers to come back. The Lions could have continued to run the ball and drain the clock.

Props to the 49ers for capitalizing on the Lions' mistakes and doing what needed to be done to complete the comeback.
