Trying to help Fuller owner

I would like to give him some options since he needs to win this week and had Fuller/ K. Benjamin starting.
I would want to target Doug Martin/ Alex Collins/ Ajayi/ McKinnon (bye) since I am weak at RB and maybe Kelvin Benjamin if I can.
What should I package together to target these players?

Full PPR, 12 team league

My Team:

QB: Mariota, Dalton
WR: Hopkins, Robby Anderson, Robert Woods, Pryor, JuJu
RB: Gilly, Bell, Mack, Damien Williams, Smallwood (soon to be dropped)
TE: Evan Engram, Jared Cook

His Team:

QB: Drew Brees
WR: Fuller, K.Benjamin, Bennie Fowler, Alshon Jeffery, Rishard Matthews
RB: Gordon, Ajayi, Martin, Collins, McKinnon, West
TE: Hunter Henry, Jason Witten

bumping up for ideas!
