Robert Woods and Zach Ertz for Mark Andrews and Joe Mixon?

Half ppr, 12 team. Should I trade ertz and woods for andrews and mixon. I really need a second rb, and don’t really need woods.
This is my current team:
QB - Wentz, Rivers
RB - Kamara, Guice, Adrian Peterson, Gio Bernard, Gus Edwards, Hunt, Nyheim Hines
WR - Julio, Woods, Lockett, Fitzgerald, Hollywood, Tate
TE - Ertz, Herndon
