Draft Zeke, DJ, Hopkins, or Thomas

In an 8-team keeper league expecting McCaffrey to go #1 overall (I have 2nd pick) (Saquon and Kamara kept on other teams). My keeper is James Conner. Already having Conner, should I stack up my RB with either Zeke or DJ or get a dominant receiver in Hopkins or Michael Thomas? Which of these would you take given the situation? Based on other keepers, the worst case scenario for WR at 2nd round would be Amari Cooper / Keenan Allen. Appreciate the opinions!
