I understand that if you play from behind a lot, you have more chances...there is that element.
But you are at this point making things up. The Colts didn't deliberately run the ball early to keep the games close to make plays to win late. Manning was always at the top of passing attempts.
Drew Brees had 6 4th quarter comebacks in 2018 and they went 13-3. So you're A) Your team sucks or B) maybe you do as a QB
Being down by 1 point in the 4th means it's a 4th quarter comeback. It's like you're saying all these come backs, they are down multiple scores and struggled early before they picked it up.
