They could do a slot WR by committee type of approach including using Pollard as the slot WR. - In sets with both Pollard and Zeke in the backfield, Pollard is taking the place of a slot WR.
Tony Pollard needs a dramatic increase in offensive snaps.
We can do so many things with him and Ezekiel Elliott on the field together.
I'm more concerned about the backup outside WR. - Not only as an injury backup but starting WRs don't generally play 100% of the offensive snaps.
And Amari Cooper really needs to have his snaps monitored.
I love the player, but Coop is always dealing with various injuries. He doesn't get near enough credit for playing through things lots of his NFL brethren would not. That said, it would be best to give Cooper more breaks during games provided someone emerges to handle such a reserve role.
Given the WR depth in this draft class, I expect to be drooling over possible additions all day Saturday even if Dallas addresses the position during rounds 1-3.
Whatever the Cowboys want, a big outside, small slot, big slot, WR/returner, they can get it.
