Baltimore is 1-5, and depending on how the next three weeks go, the team could be looking to make wholesale changes at several key positions and at the head coaching spot. With 11 games remaining, most prognosticators believe the Ravens need to win at least nine to secure the likely double-digit wins required to earn one of the final AFC wild-card spots. 

At 4-1, Pittsburgh is currently three wins ahead of Baltimore in the AFC North, but the Ravens have the fifth-lowest strength of schedule in the NFL remaining (.442), with their most challenging matchups being the Steelers (twice), Packers, and Patriots. Baltimore is on a bye week, and will face the Bears (Oct. 26) and Dolphins (Oct. 30) before the November 4 trade deadline.

With the bye week nearly complete, here’s a look at the highest and lowest graded from the Ravens’ offense and defense after the first six games via Pro Football Focus.
