Green for D Murray?

Standard scoring 2 RB, 2 WR, 2 Flex. I have Elliott and Bell, Murray and Coehn at RB, Beckham, Jeffery, Thielen, Watkins and D Parker at WR.
Should I take Green for Murray?

Do you have any other bench players? I would feel uncomfortable being left with only 3 RB’s on my roster.
