I actually think there are quite a few interesting options for a WR in the later stages.
My favourite is Tamorrion Terry of FSU, 6'4" and speed to burn, think he will be there in the 4th round which would be useful seen as we lost one of our 3rd rounders.
Ihmir Smith Marsette of Iowa is another speedy option who should be there in the 4th.

Other options are Warren Jackson, Josh Imatorbhebhe, Elijah Moore, Trevon Grimes and, as you say, D'Wayne Eskridge. I think we need to seriously think about trading Woods or Kupp and going for a deep threat. With our OLine and Edge needs taking priority, I think we need to look for a WR in the 4th round.
