Should I drop this player for Diggs?

Full point PPR-My running backs are Shady Gordon Martin CMC and Mixon-I just picked up Fuller to go with Hill and Allen-Nobody trades etc so should I just go ahead and drop Mixon or CMC for Diggs?

I’d drop mixon

i also have kamara-- Would you drop Mixon for Diggs and that strengthens my wr core-1 point per rush and 2 points per catch-just thinking long term as hill goes up against denver last game of season-thanks

should i drop mixon for diggs???
