Basketball refs using clock technology to get it right
In this photo taken March 8, 2019, a referee prepares to start a play using a Precision Time device during the first half of an Atlantic Coast Conference women's tournament basketball game in Greensboro, N.C. The Precision Time system created more than two decades ago by former referee Mike Costabile currently is used at nearly every level of the sport, including the NBA and college basketball's NCAA Tournament. Costabile estimates the ability to stop the clock automatically on a referee's whistle can save roughly 90 seconds formerly lost to reaction time when timekeepers manually stopped the clock.
