Fifty years ago it was uncommon to have the pins anywhere near the
edges of the greens. As players' skills improved, the holes were
gradually allowed to be moved closer to the edges, first to ten paces
away, and then five, and then four, and now three. This has had the
effect of making the Greens in Regulation statistic much less
valuable, as it is better to be putting from the fringe 12 feet away
than on the opposite side of the green, but still on it, 80 feet away.
Anyway, pro golfers have adjusted, so the PGA is announcing that
starting in 2014, up to three holes each round may have the pins up to
three paces (or yards) off the green. If this experiment is well
received, then in 2015 up to six holes per round may have pin
placements up to five paces off the green.
