What other factors go into the decision? Field position. In a close, defensive game the battle for field position could decide the game. The better position you can set your offense up in, the easier it is to score. Failing to covert on a 4th and goal from the one would put the 49ers in the worst field position possible starting in the shadow of their own end zone. Another factor is your belief in your own defense. If you believe your defense can hold them that’s another reason to roll the dice and go for it. Ron Rivera has one of the best defenses in the league. They finished ranked 2nd in total yards allowed and rushing yards allowed and were led by All-Pro ILB Luke Kuechly and Pro Bowler defensive end Greg Hardy. A quick stop leads to a punt and that leads to good field position on your next drive.
Rivera decided to go for it and Newton tried a quarterback sneak but was met in the hole by Ahmad Brooks and stopped inches from the goal line giving the ball back to the 49ers. The Panthers defense held firm only allowing the 49ers two yards before forcing a punt by the Niners from their own end zone. The punt was fielded by Ted Ginn Jr. and returned 24 yards to the 49ers 31 yard line and on the very next play Cam Newton connected with Steve Smith for a 31 yard touchdown.
So Rivera’s decision ended up getting the Panthers a touchdown despite failing on 4th down. Rivera’s belief in his team in all three phases was rewarded. He trusted the offense to not only get the yard but if they couldn’t to go right back down and score when given the chance. Rivera believed his defense would not let San Francisco get 1st downs and flip field position and he believed he had one of the best punt returners in the game in Ted Ginn Jr.. So the next time Rex Ryan goes for it on a 4th and 1 (or doesn’t) think about all the factors that go into his decision before you criticize because he may be right it just may take a little while for the results to show.
