Need help with large keeper league

It’s a 10 people PPR superflex (1qb,2rb,3wr,1te,1flex,1Sflex) and we get to keep 12 players (first 12 rounds everyone). I’m pretty stacked at WR and want to trade but not sure who I should be going for … Also struggling with who to keep if I don’t trade.

QB: Rodgers
QB: Mahomes
QB: Teddy Bridgewater

RB: Bell
RB: Conner
RB: Lindsay
RB: R. Freeman
RB: Ballage
RB: Dixon

WR: OBJ
WR: Diggs
WR: Westbrook
WR: Godwin
WR: Golladay
WR: Pettis
WR: Watkins
WR: DeSean Hamilton
WR: A. Miller
WR: MacKenzie

TE: Ertz

Which 12 would you keep?

Which RBs should I Target and with what players?
