CB Marcus Peters

Peters had an interception and fumble recovery in his second game back from last year's torn ACL. Now his speed and savvy will be put to the test by Diggs. Peters has shaken off the rust, and this is the kind of matchup he loves.

S Marcus Williams

The Ravens brought Williams to Baltimore to cut down on the deep shots. That's Allen's specialty, as he's unafraid to let it rip down the field. Williams leads the NFL with three interceptions. He will be lurking, looking to snag any off-target Allen throws.

WR Rashod Bateman

The Bills are banged up in the secondary with safety Micah Hyde (neck) on IR and top cornerback Tre'Davious White still sidelined. That gives the Ravens some chances to hit big plays. Bateman leads the NFL with 28.3 yards per catch (eight for 226 yards).

RT Morgan Moses

Moses has one of the league's toughest assignments, to block likely future Hall of Fame pass rusher Von Miller. No active player has more sacks than Miller's 117.5 and he's still playing at a high level with 2.0 sacks on the young season. Moses has done well in pass protection this year, allowing just one sack and two hurries in 99 pass blocking reps, per Pro Football Focus.

OLB Odafe Oweh

The Ravens need to make sure Allen feels some pressure yet doesn't get out of the pocket and beat them with his legs. Allen is always a threat to run, especially to move the chains on third down. Oweh is looking for his first sack, but also has to stay disciplined. If there's one guy on the Ravens defense with the size and speed to track down Allen, it's Oweh.
