Need WR and RB help

12 team league, standard scoring. I need two of each and a flex.

WR options: Amari Cooper, Golden Tate, Terry McLaurin, and Allen Lazard

RB options: Le’Veon Bell, Mark Ingram, Latavius Murray, Devin Singletary, and Chase Edmonds

Between matchups and injuries, I’m so lost this week on who to play. I’m leaning away from Cooper because I’m scared he won’t last even a whole quarter. The matchups for McLaurin and Bell also have me really concerned. Any advice would be appreciated.
