(Reuters) - "Football players don't have any clue." That was the verdict of Olympian Mike Rodgers as National Football League wide receiver DK Metcalf prepares to compete in the 100-metre sprint at Sunday's USA Track and Field (USATF) Golden Games and Distance Open in Walnut, California. The Seattle Seahawk, who posted a 4.33-second, 40-yard dash at the 2019 NFL combine, is competing in hope of earning a spot at next month's U.S. Olympic Track and Field Trials.
