Why the Browns can cover

The Browns have some advantages in this matchup on the defensive side, particularly with Pittsburgh's recent struggles to move the ball offensively. However, Cleveland also has real talent offensively, and the Browns have the ability to generate efficient offense against the stout Pittsburgh defense. 

The Browns were a top-five rushing team in the league this season, averaging 148.4 yards per game with 21 rushing touchdowns, and Nick Chubb finished in the top seven of the league in rushing yards (1,067), rushing yards per game (88.9), yards per carry (5.6) and rushing touchdowns (12). 

Cleveland also has an elite complementary back in Kareem Hunt, with 841 rushing yards and six touchdowns in his own right. Through the air, Baker Mayfield took care of the ball at a solid level this season, and Jarvis Landry is a proven pass catcher, leading the team with 72 catches for 840 yards in limited deployment.

Why the Steelers can cover

Defense and special teams often come to the forefront in the NFL, and Pittsburgh is excellent in both areas. The Steelers led the league in sacks (56), passer rating allowed (76.7), interceptions (18) and completion percentage allowed (56.7 percent) this season, and their success went beyond that. The Steelers were also a top-five unit in total defense, scoring defense, passing defense, yards per pass attempt allowed and passing touchdowns allowed. 

Pittsburgh is adept at getting off the field on third down, allowing opponents to convert just 37.4 percent of the time, and when they do, Pittsburgh's special teams take care of business. Ray-Ray McCloud is a top-10 player in both punt and kick return yardage, finishing fourth in the regular season with 944 total return yards. Chris Boswell is also a tremendous kicker, making 95 percent of his field goals this season.
