Punters don’t really play football.
They, and placekickers, are the only ones who do. The rest cheat and use their hands and block and stuff. < /s>
But they come in handy when the regular players don’t play well.
I know several high school and college punters who played other positions well. One linebacker on the local HS team was called into service to punt after the punter went down on the previous punt. Kicked the ball from the end zone to the five yard line of the other team with a 15 yd roll.
