Overview

• Built on Sony’s Hawk-Eye technology, the system uses six 8K cameras to track the ball in real time.
• Officials invoked the virtual measurement tool during a second-quarter Lions run at the Hall of Fame Game to determine the line to gain.
• Outcomes are displayed instantly on stadium videoboards to enhance transparency for fans and officials.
• Virtual measurements cut average decision times to about 30 seconds versus 75 seconds with the traditional Chain Gang.
• Season-long evaluations could see the century-old Chain Gang retired if the virtual system proves reliable.
