If the model is correct then everything you mention is already accounted for, that is the point.
First bolded - yeah it si easier to stop them from own 10 than 25, but in first case you lose by 7, whereas in second scenario you only lose by 4. Thats the difference. TD wins the game.
Second bolded makes little sense. If you are not getting the ball back, you already lost the game. They have 4.37min and a good kicker. There is NO WAY you win that game without getting the ball back, thats the point.
