Ron Rivera refused Tuesday to reveal who will start at quarterback for the Washington Commanders in their season finale this weekend against the Dallas Cowboys. It could be an 18th consecutive start for Sam Howell, the first of the season for Jacoby Brissett or even Jake Fromm's first NFL game action in nearly two years. “We don’t have to let anybody know until tomorrow, so we’re just going to wait,” Rivera said on a video call with reporters.
