Biggest threat on offense: Is Flacco elite? Unlikely. But he has the weapons to thrive this season with the return of wide receiver Steve Smith Sr. and tight end Dennis Pitta and the addition of wide receiver Mike Wallace via free agency. They’ve been Flacco’s top three targets so far, as he’s thrown for 1,072 yards, four touchdowns and four interceptions.

Biggest threat on defense: He’s 33 years old, but outside linebacker Terrell Suggs can still get the job done. He’s tied for a team-high three sacks after coming off an Achilles’ injury he suffered during the season opener a year ago that forced him to go on injured reserve. Suggs’s presence creates opportunities for other defensive players to get to the quarterback. Baltimore has recorded nine sacks this season, and it has the top-ranked defense, allowing just 256 yards per game. The Ravens have given up just 18 points per game, seventh best in the NFL.

Key injuries: Sunday could mark the debut of rookie running back Kenneth Dixon, who has been sidelined through the first four games because of a knee injury he suffered during the preseason. The Ravens released Justin Forsett on Tuesday after he was benched in Sunday’s loss to the Raiders, a sign that Dixon should be ready to go against the Redskins. Outside linebacker Elvis Dumervil played in his first game of the season because a lingering offseason foot issue. Baltimore started the season without tight end Benjamin Watson and cornerback Kyle Arrington, who were both placed on injured reserve during the preseason.

Jay Gruden’s coach speak: “Coming from the AFC North, I know all about Baltimore. They’re a good football team, they’re well coached again. Suggs, Dumervil, those two guys are explosive guys off the edge and problems. And offensively, Flacco, we’ve already talked about him, quality quarterback. So, it’ll be a heck of a game.” – Gruden, who spent three seasons as the offensive coordinator for the Cincinnati Bengals (2011-2013) before joining the Redskins.
