Who to drop now with Ekler off IR?

I am in a full PPR league. I have to drop someone to reactivate Ekeler

QB - Goff, Tannehill
RB - Sanders, Ekeler, Gurley, B. Scott, Brian Hill
WR - C. Ridley, C. Kupp, S. Shepard, M. Pittman, M. Williams.
TE - T. Kelce

I was kind of thinking between B. Scott (handcuff), M. Williams, or M. Pittman. But I kind of like Williams with Herbert success and would hate to lose Pittman with an easy schedule and him starting to take over as the top wide out. But Scott as a handcuff is valuable. Not sure what to do.
