Yeah, football isn’t played for bettors. It is played to win games. You run out of bounds instead of scoring, because then you can run down the clock while you control the ball. You score, then you have to kick to the other team, if they score they can do an on-sides kick, and might recover it and score again. Your 7 points isn’t worth the possibility of 14 points against you, when you don’t need it.
That exact scenario happened this year when Todd Gurley of the Falcons was told not to score, get the 1st down but then fall down and the Falcons could run out the clock...
Instead when he fell down it was right on the goal line, giving the ball back to the Lions who went down and scored the winning TD on the last play of the game....
That meaningless TD cost the Falcons the game...
