Trade Advice - Davis for Singletary

half PPR, I am 1-4 (lost CMC, Sutton and Chark issues).
Lineup is QB, WR, WR, RB, RB, Flex, K, DEF
My RBs
CMC
Miles Sanders
Singletary
Antonio Gibson
Josh Kelley
Brian Hill

WR
Kupp
Chark
Higgins
Mike Williams
Alshon Jeffrey

The Mike Davis owner just offered me Davis for Singletary

I figure I may get two weeks out of Davis but I definitely need to win if I want a chance. Playing for week 6 and week 7 seems like the right thing to do even if it means a bit of a downgrade

Advice?
