Sit or start wr

My wide receivers are Jordy, Pryor, Benjamin, Allen, and Coleman. Obviously Jordy is WR1 but WR 2 is the question mark. I lean Pryor but allen and benjamin could have big games. What do you guys think? I could flex another but Iike my rbs as anderson, montgomery, and gordon. Should I take one of these guys out and start another one of my WRs? Thanks for any feedback, I have been racking my brain all week.

I also have Devante parker
