NFL teams should go for it on 4th down much more often (even if in their own territory for example), rather than almost always punting.
Essay and/or background: In the National Football League (and indeed at levels of football), coaches usually call for a punt if they face fourth down. They'll usually go for it only if they're down by a lot of a points or if they only need a couple yards and are past midfield. In a 2005 paper
(pdf), economist David Romer presented an analysis arguing that teams would be better off going for it more often. Seeing this, Coach Kevin Kelley of the Pulaski Academy instituted a strategy where his team very rarely punts, and it seems to have paid off. The national press recently noticed the Arkansas high school's strategy, and it's raised the issue -- what if they tried that in the NFL? Even if they don't go so far as to never punt, I hold that NFL teams should go for it much more frequently than they do now.
Cruxes...
The top point in support right now is, "Since 2006, Pulaski Academy hasn't had a punting unit or practiced punting. In 2006, they reached the state championship and this year are 9-1-1. That's a success."
The top counterargument is, "NFL coaches are smart and highly motivated -- the fact that they don't go on 4th much (and historically haven't) is support for not doing so."
