INGLEWOOD, Calif. — Justin Strnad couldn’t believe the yellow laundry on the field. He pleaded with the Thursday night officiating crew on the field after he was flagged for unnecessary roughness on Chargers quarterback Justin Herbert, but to no avail. After the game, he tried to hold his tongue when asked about the critical third-quarter penalty that turned what would have been a fourth-and-4 at the Broncos’ 11-yard line into a first-and-goal at the 5 because Strnad made contact with Herbert while he was sliding down to the ground. “I don’t really have any comment,” Strnad said after Denver’s 34-27 loss.
