Ignoring all the dumb Reddit-ass “joke” answers, it helps a lot when you can shoot short of the sticks or the endzone. It completely changes how a defense had to defend third down. All of a sudden if you’re protecting the sticks a decent run by a RB gets them in position for an easy 4th down conversion. But then if you try to prevent them from getting into push range you’re potentially giving up bigger chunk plays.

edit I think the redzone it has the biggest advantage. Normally the defense would be at an advantage because they’re defending a much shorter field, but then they also have a tendency to defend past the pylons instead of before them.
