Rashaad Penny for Devin Singletary

I am currently in a .5 PPR 10 man league. Should I drop Penny for Singletary, both are in a RBBC, everything in my gut tells me yes because of the loadshare for Carson. I have tried packaging Tyler Boyd with Penny to teams weak at WR for RBs drafted around the same round.

My roster for RB is: (Start 2 + Flex)
Ezekiel Elliott
Damien Williams
(Had Lamar Miller from Hou)
Tevin Coleman
Tony Pollard
Rashaad Penny

WR: Start 3 + flex
Julio Jones
Tyreek Hill
Robert Woods
Tyler Boyd
Robbie Anderson
Dede Westbrook
Josh Gordon

Other notable available RBs:
L. Mccoy
C. Hyde
Justin Jackson
Justice Hill
Alexander Mattison
Damien Harris
Frank Gore
