The technology is already being used by pro and college teams; at February’s NFL combine, would-be football players’ initial acceleration in the 40-yard dash was tracked by sensor-equipped shirts. The data also could change the way fans watch their favorite sports. “[D]evice makers and the sports industry seem most excited about the prospects for entertainment.
