Murray for K Allen

What do you guys thinking about Murray for Allen in a 12 man .5 PPR?

Struggling with crab on bye and evans being suspended.

My Current Roster is:
QB: Cousin, Rivers
RB: Murray, Martin, Powell, Henry, Cohen, Woodhead
WR: Evans, Crabtree, Adams, Rish Matthews
TE: Kelce, Olsen
D: Ravens
K: Buttkicker

is Cohen worth having in .5ppr over Murray? With woodhead coming back Allen is gonna take a backseat. It seems like Murray still have more value in the Titans offense than Allen does at this point.

I should have been more clear on which Allen, whoops. We are talking K Allen WR for the chargers.
