Trade help! Trade Thielen for Carson?

Should I trade Thielen for Chris Carson in full PPR? I just lost Saquon and my other RBs are Sony, Tarik Cohen, Breida and Chris Thompson. Other Receivers are Keenan Allen, Kupp, John Brown and Christian Kirk

2WR, 2RB and a Flex league?

Yeah feel like my depth at receiver might be good enough but I don’t know how to feel about Carson’s slow start.
