Tulsa Washington’s star running back took the slow handoff, cut, found a crease and raced down the field. Ninety-nine yards untouched. “I just took off,” Grayson said. “Oh my God,” added Tulsa Washington coach Brad Calip. “He looked like the old Grayson again.” Del City’s chance to stay in the game against the Class 6A-II defending champion was dashed in heartbreaking fashion early in the fourth quarter with the longest play possible in a high school football game. Grayson’s near field-length run sparked a second-half dominance for No. 4 Tulsa Washington as it beat No. 5 Del City 27-8 to open the playoffs Friday night at S.E. Williams Stadium. “That was obviously the backbreaker,” Del City coach Mike Dunn said. “They got big there in the second half. Credit to them for running right at us.” Grayson, who was once committed to Nebraska and is ranked No. 11 on The Oklahoman’s Super 30, finished with 285 yards and one TD.
