Seattle Seahawks wide receiver DK Metcalf will venture into new territory this weekend to test his speed. Metcalf has accepted an invitation to run the 100 meters at the USA Track and Field Golden Games in Walnut, California. The competition will include Olympic-caliber sprinters. Metcalf’s decision to run has captured the attention of the track world, where athletes for years have been challenged by anyone in any sport who just happens to be fast. This may be their chance to show once and for all that track speed is far different from football speed.
