Look at how many college and pro games are decided by 3 pts. or less. Look at how many games are lost on missed extra points. And don't forget the punters, they change field position when the offence goes 3 and out. PUNTERS and KICKERS DECIDE THE GAME.
It's not always the distance that counts boyz, hangtime is more important. If the return man can't return and the punter can pin the other team inside the 10 and make them try to go 90 yd. for TD, then he is the most dangerous defensive man on the field.
