This is the fourth part of the offseason series that is focusing on the Baltimore Ravens' position groups as they continue organized team activities (OTAs) this week. This post will look at the Ravens' wide receivers.

Returning: Steve Smith*, Kamar Aiken, Marlon Brown, Michael Campanaro, Jeremy Butler (injured reserve), Aldrick Robinson (practice squad)

Newcomers: Breshad Perriman* (first round), Darren Waller (sixth round), DeAndre Carter (undrafted rookie), Daniel Brown (undrafted rookie), Cam Worthy (undrafted rookie)

Departures: Torrey Smith (free agent, signed with 49ers)

Roster spots likely available: Five or six

Competition: Aiken vs. Marlon Brown for the No. 3 job. The Ravens are counting on their oldest receiver (Smith) and one of their youngest (Perriman) to handle the top two spots. There are plenty of catches up for grabs after that. Marlon Brown and Aiken essentially split the No. 3 receiver role last season after Jacoby Jones struggled and each finished with 24 catches. Both have good size and are possession-type receivers. Aiken stepped up last season when Torrey Smith was injured, and Brown is a season removed from catching 49 passes. If the Ravens had more cap room earlier in free agency, they likely would've brought in a more experienced receiver to improve the depth at this position. For now, the race for the third receiver spot is down to Aiken and Brown, especially in light of the recent injury to Campanaro. He was expected to figure into the rotation as a slot receiver.

Outlook: The Ravens selected a wide receiver in the first round for the first time in a decade, and they're hoping Perriman can replace the big-play ability of Torrey Smith. In order for Perriman to make an immediate impact, he'll have to break a couple of trends for Baltimore. No Ravens receiver selected in the first two rounds has started the season opener in his first season, and only one rookie in team history has produced over 550 yards receiving (Torrey Smith). Steve Smith is the Ravens' only proven starting receiver, and coach John Harbaugh mentioned at the end of last season that Smith's snaps might be reduced to lessen the wear and tear on his 36-year-old body. Last season, Smith totaled 675 yards receiving in his first eight games (seventh-most in the NFL) and 390 yards in his last eight (53rd in the league). The Ravens could carry a sixth receiver depending on how a young receiver like Waller, Butler or Carter fares in the offseason and training camp.
