Wide Receiver Help!

Looking to boost my starting wide receivers. I feel confident with OBJ but not really with any of my other options. Any ideas of who to target or potential trade offers?

Ty Montgomery
Mark Ingram
Terrance West
Tarik Cohen
Shane Vereen

Jamison Crowder
Jeremy Maclin
Sterling Shepard
Cooper Cupp

I also have Gronk & Zach Miller as TEs (picked up Miller in the event Gronk was out last week)
