The biggest question mark at WR for the Steelers, as noted by Joe Rutter of the Pittsburgh Tribune-Review, comes at the slot position.
Yes, JuJu Smith-Schuster could operate from the slot, if the team feels comfortable with rookie second-rounder James Washington in an outside role.
Veteran candidates include Justin Hunter and Darrius Heyward-Bey. Rutter thinks Marcus Tucker, a practice-squad player in 2017, could earn a roster spot specifically to play in the slot.
Eli Rogers, who suffered a torn ACL, is still looking for work. The Steelers could bring him back, and he could earn reps in the three-receiver set.
The story puts it best, whoever gets the gig should have favorable matchups, given the attention that will be paid to Brown and Smith-Schuster. Which will put even more pressure on the slot receiver to perform.
