The Dolphins and the Vikings found out the hard way. If Mike Wallace is a one trick pony, the Ravens should think smarter, and not for him into roles he has previously failed in.
His contract however, seems to indicate that the Ravens think of him as a legitimate number two receiver. While that projection could come to fruition, it is exactly that. A projection.
When Wallace was signed, most pointed to his role being similar to that of Jacoby Jones' in the 2012 receiving corp. A deep threat that would contribute in spot duty.
Wallace is at his best running nine routes. Breshad Perriman, splitting with Kamar Aiken across from Steve Smith should provide the best duo when two wider receiver sets are employed.
Wallace wold do his best work coming on the field with Breshad Perriman and Steve Smith in the slot. With the designated tight end also on the field, Wallace would not have to play outside of himself. He could concentrate on what he does best, and having other receivers to run the more precise routes would free him up to run curls, posts and nines.
