Trade Mixon for D Williams and M Sanders?

Guy in my 10 team PPR wants my Mixon for his Damien Williams and Miles Sanders. Don’t love trading for two guys in potential RRBCs, but Mixon injury and Gio Bernard could make that somewhat of a time share too.
My current RBs - Saquon, Sony, Mixon, Melvin Gordon, Justin Jackson, Chris Thompson

There are still some question marks around both those guys. I would wait until after week 2 to see if Williams will continue to put up those numbers and if sanders will beat out the other two to take the lead role. You have enough depth to wait on Mixon to come back.
