Outlook: The losses of Mike Wallace (free-agent departure to the Philadelphia Eagles) and Jeremy Maclin (offseason release) left a void in experience that prompted the club to pursue Crabtree, Snead and Brown. Perriman and Brown have the speed to replace Wallace, but developing the trust that Flacco had in Wallace is another matter. Moore is a reliable option in the slot or on the outside, but he might be hard-pressed to earn playing time. Mayle is making the transition from a crowded tight end position to wide receiver. Despite being fourth- and fifth-round selections in May, Scott and Lasley, respectively, will have to prove that they are worthy of spots on the active roster.
