The Ravens appear to have their starting boundary tandem in place at the cornerback position. A number of candidates are vying for the first-team role in the slot, however.
Marlon Humphrey is in place to once again serve as the anchor of Baltimore’s secondary, but fellow All-Pro Marcus Peters is no longer in the fold. The latter signed a long-anticipated deal with the Raiders recently, marking a formal end to his Ravens tenure. Rock Ya-Sin had already been acquired as a Peters replacement, signing a one-year contract in May. The former Colt and Raider is currently dealing with a knee injury, but it is not believed to be serious (Twitter link via Ian Rapoport of NFL Network). 
The question of who starts in the slot remains unanswered. Defensive backs coach Chris Hewitt named several contenders for the role, as detailed by The Athletic’s Jeff Zrebiec (subscription required). Among them is a mix of veteran and young players, as well as those with a background playing at safety as opposed to corner, and vice versa. Hewitt said the position is in an “open competition” at this point.
2022 first-rounder Kyle Hamilton played extensively in the slot as a rookie, but the trade sending Chuck Clark to the Jets paved the way for the Notre Dame product taking on full-time safety duties. The Ravens used three-safety alignments under defensive coordinator Mike McDonald, however, so keeping Hamilton at the nickel could allow the Ravens to deploy their best secondary options for extended stretches.
Other candidates for the position include Brandon Stephens and Ar’Darius Washington. The former was a third-round Ravens selection in 2021, after a college career which saw him play at both running back and corner. Stephens primarily played as a safety as a rookie, but his more common usage came at corner in 2022. Washington, meanwhile, has seen time in the slot in his limited usage since joining Baltimore as a UDFA.
2022 fourth-rounders Damarion Williams and Jalyn Armour-Davis are also contenders for a first-team role. Williams was named as a player to watch during camp, given his more natural fit as a slot corner compared to many of the team’s other options. He missed time at the start of camp due to injury, however, leaving him with ground to make up during the preseason. Hewitt added that Armour-Davis, who played on the outside at Alabama, is under consideration to be moved inside.
By far the most experienced option is Arthur Maulet. The 30-year-old signed a one-year deal last week after being released by the Steelers earlier in the offseason. Maulet has seen considerable usage in the slot over the past three seasons in particular, and it would come as little surprise if that is his primary function in Baltimore. The Ravens were linked to a veteran signing leading up to his addition, but another could be coming as well.
Zrebiec notes that the Ravens could still be in the market for a corner, though the team is focusing on its numerous internal options for the time being. The developments in the ongoing competition will be worth watching as camp practices and preseason games take place.
