NFL Week 3 recap: the defending Super Bowl champs lost to a backup quarterback. Marcus Mariota threw three touchdowns with zero interceptions as Washington beat Seattle 33-31 and ended their 12-game win streak. Atlanta outrushed Green Bay 242 to 17 at Lambeau, and Denver came back from 16 down on a walk-off pick six. I've got the Steelers over the Browns on Thursday. Steelers or Browns? #nfl #nflweek3 #seahawks
