Trade Help - Chris Carson Owner

Would you trade Demarcus Robinson for Rashad Penny? .5 PPR League

My RBs are: Dalvin Cook, David Johnson, Chris Carson, and Darrel Williams

My other WRs are: Tyler Lockett, Brandin Cooks, Tyler Boyd, Emmanuel Sanders, Mecole Hardman, Marvin Jones Jr.

With so many receivers, I figure this will help RB depth and also give some safety to being the Chris Carson owner should the fumble problem continue.
