Timeouts before Free-Throws: Do the Statistics Support the Strategy?

Abstract

Basketball coaches often call a timeout just before the opposing player shoots a free-throw during the last five minutes of a close game. Their intent is to lower the opposing player's free-throw percentage. This study examined the effectiveness of this strategy in critical game situations. Play-by-play records of 1237 men's NCAA Division I games played between 1977 and 1989 were reviewed. We identified 350 verifiable timeout situations. Opposing coaches called 250 timeouts before an opponent shot a free-throw. As the score differential and time remaining in the game decreased, coaches relied on this strategy more frequently to try to control the outcome of the game. This strategy was not effective in reducing free-throw percentage, suggesting that coaches need to reconsider the strategy.
