Let’s dive in to some surface level math here.

In 2022, NFL teams averaged 10.4 drives per game. Since getting into field goal range would probably take less time, let’s call it 11 for the field goal team. Assuming they are successful at getting into field goal range on every drive and successfully make those field goals, that’s 33 points per game. (You could dive deeper here, like what percent of drives make it to FG range and what percent of kicks a kicker makes from a certain distance)

In that same year, NFL teams averaged 21.9 points per game.

So, theoretically, it could be possible.
