Drop Murray for Flex Players?

Thinking about dropping Murray since Cook is slated to come back.

My Team:
WR: Diggs, Tate, Fitzgerald, Sutton, Watkins
RB: Gurley, Mixon, Ekeler, Murray, Hines, Brown(handcuff)

Devante Parker, Allen Robinson, Chris Godwin, Coutee and Royce Freeman are all available on waivers.

Also should I drop Hines for one of these players?
