So Why Can't Shaq Make Free Throws?

The NBA league average for free throw shooting is about 75%. Shaquille O'Neal's career average is 52.4%. Even worse, Ben Wallace's career average is 41.9%. The average for the NCAA Division 1 teams is 69%. The obvious question is why can't Shaq or Ben or Memphis do any better, but the bigger question is why do most of the best basketball players in the world miss 2 or 3 free throws out of 10? Maybe they just haven't heard about Joan Vickers and the "Quiet Eye".

For me, the best science is applied science. The same goes for sports science. Theories, physics, psychology, etc. are only useful in sports if they can be used to improve in-game performance. That's why I have always been a fan of academic work that leads to useful techniques in the field. Professor Joan Vickers of the University of Calgary has been applying her research into the human visual system and its effects on sports performance for over 25 years. She is the discoverer of the "Quiet Eye" skill that has been shown to significantly improve accuracy in targeting and decision-making skills in many sports. In addition to this "gaze control" technique, she also has developed a 7-step teaching process to improve the in-game decision-making of athletes, based partly on their visual perception skills.

She has a new book out that condenses all of these ideas, called Perception, Cognition and Decision Training. Over the next few days, I will do my best to paraphrase and explain the most useful information and techniques, but of course the best source is this book.
For an opening primer on the Quiet Eye, please take a look at this episode and this online video of PBS' Scientific American with Hawkeye himself, Alan Alda, shooting free throws.
