A half century of bricks

The New York Times is reporting that free throw statistics in professional and college basketball haven't changed (for better or worse) in 50 years. With all else that's improved in the sport over the years, you'd think that the easiest shot would have gotten easier. Wilt Chamberlain, by the way, a guy who could score a 100 points in a game was so bad at free throws that he resorted to a two-handed underhand shot that improved his scores only slightly.
When I was in high school, our basketball team was behind by one point with about two seconds left to play. Our star player was fouled and had two free-throw shots.
"Don't worry, coach," he said. "I'll make 'em both."
