There's no tougher defense in the NFL than the Steelers when it comes yards allowed.
Pittsburgh leads the NFL in total defense, giving up 257.2 yards per game. There's only one other defense holding offenses under 300 yards per game, and that's the 49ers. Still, San Francisco allows 278.4 yards per game, which is 21 more yards than the Steelers.
The Steelers have been on a tear recently, holding teams to fewer than 300 yards in six straight games. That's the longest streak by any team since the 2010 Dolphins, according to ESPN Stats & Information.
Could that streak come to an end in Baltimore? The Ravens only gained 200 yards against the Steelers a couple of weeks ago, but they are a different offense at home. In five games at M&T Bank Stadium this season, the Ravens haven't been held under 300 yards. Their offense is averaging 421.2 yards at home this season.
The Steelers also rank fourth in fewest points allowed this season (19.1 points). That will also be tested by the Ravens. They have scored an average of 36.8 points per game at M&T Bank Stadium this season, ranking as the NFL’s best mark among home teams. Baltimore has scored at least 31 points in four of five home games this season, and at least 44 in two contests.
