Free-throw shooting

I came across this article today about free-throw shooting. It questions free-throw percentages haven't improved over the last 50 years, while other achievements in sport improve with time.

For Free Throws, 50 Years of Practice Is No Help - NYTimes.com

CEDAR CITY, Utah — Basketball in the United States has changed in myriad ways over the decades, from flat-footed set shots to dunks, from crotch-hugging uniforms to baggy knee-length shorts, from the dominance of American players to the recent infusion of international stars.

But one thing has remained remarkably constant: the rate at which players make free throws.

Since the mid-1960s, college men’s players have made about 69 percent of free throws, the unguarded 15-foot, 1-point shot awarded after a foul. In 1965, the rate was 69 percent. This season, as teams scramble for bids to the N.C.A.A. tournament, it was 68.8. It has dropped as low as 67.1 but never topped 70.

In the National Basketball Association, the average has been roughly 75 percent for more than 50 years. Players in college women’s basketball and the W.N.B.A. reached similar plateaus — about equal to the men — and stuck there.

The general expectation in sports is that performance improves over time. Future athletes will surely be faster, throw farther, jump higher. But free-throw shooting represents a stubbornly peculiar athletic endeavor. As a group, players have not gotten better. Nor have they become worse.

“It’s unbelievable,” Larry Wright, an adjunct professor of statistics at Columbia, said as he studied the year-by-year averages. “There’s almost no difference. Fifty years. This is mind-boggling.”

No pressure ... can you make a free-throw when it matters most?
