As a non-golfer, I am perplexed by this whole business of conceding putts. A basketball player with an uncontested breakaway steal still has to make the shot. A football wide receiver who gets loose in broken coverage still has to catch the ball and cross the goal line. And in the NFL, where 99.6 percent of extra-point attempts are converted, the kicker still has to boot the ball. Why should anything, ever, be conceded in a sport or game where score is being kept?

In the NFL in 1979, there was some suspense on extra kicks, they only converted 91% of them.  So last year, during the preseason, they tested 33 yard extra points, and the conversion percentage went down from 99% to 94%.  So in 2015, the NFL is moving the extra point line to the 15 yard line.
Yes, but they realized that it was so bogus, they just positioned extra points (by kick) to the 15 yard line from the three yard line.
