The Pittsburgh Steelers used a second-round pick on James Washington at wide receiver before spending a 2019 fifth-round pick in order to add Ryan Switzer in to the mix as well (they also got a sixth-round pick back in that trade). With Antonio Brown and JuJu Smith-Schuster, the team seems to be so content with the group that they have been using all of them on the field together over 10 percent of the time.
That is not to mention special teams ace Darrius Heyward-Bey, who gets called upon to run a go route or to carry out a blocking assignment here and there, and Justin Hunter, whose inability to participate on special teams and the number of bodies at the position finds him a weekly healthy scratch unless there are injuries that enable him to dress.
