THOUSAND OAKS, Calif. — Los Angeles Rams coach Sean McVay says he’s likely responsible for the NFL memo sent Monday to reinforce that coaches must wear face coverings at all times on the sidelines during games and threatening discipline for those who don’t comply. “I figured that memo was directed at me,” McVay said Monday evening during a video conference with reporters. During a season-opening victory over the Dallas Cowboys in front of a Sunday Night Football television audience, McVay roamed the sideline with his mask mostly worn under his chin, a clear violation of the league’s coronavirus safety protocol. “I’ve been getting blasted all day about it, so I just love it,” McVay said, a bit tongue-in-cheek, before continuing in a more serious tone. “I will do better.” In contrast to McVay, Cowboys coach Mike McCarthy, when shown on the NBC broadcast, appeared to wear his mask throughout the 2-hour, 56-minute game.
