Is this version of the Steelers' defense here to stay? The Steelers' defense put together its best showing of the season in Sunday's win over the Vikings, teeing off on QB Carson Wentz and a handful of backup offensive linemen to collect six sacks and 10 tackles for loss. The return of S DeShon Elliott was crucial in thwarting RB Jordan Mason and the rushing attack, and Elliott also came up with a big second-quarter interception. LB T.J. Watt dramatically affected the game, too, with a third-quarter interception when he batted the ball down at the line of scrimmage and grabbed it out of the air. Even DT Keeanu Benton, who had a tough start to the season, got in on the action with two sacks.

While the defense was solid for most of the afternoon, big plays still came back to bite them when Jordan Addison's 81-yard catch-and-run set up Jalen Nailor's late fourth-quarter touchdown. Even so, the Steelers' defense spent most of the afternoon in the backfield. They will aim to import this performance back to the States and keep the momentum going after the Week 5 bye.
