RB Help! Buck allen, shady, cj anderson, mccaffrey, kelley

So we have full point PPR, 2 point bonus over 100yds, 1 point/10yds.
At this point, based on production I’m planning on starting mccaffrey and shady for sure. I’m thinking of running buck as my flex… Receivers are running a bit thin in my league. Would you pick up and run funchess instead? Looks like he’s still out there… CJ has been a bit of a dude lately since Denver hasn’t really seemed to put anything together lately. I also have amendola but I’m not sure he’ll do anything spectacular.

Current starters:
Javorius Allen
AJ Green
Hunter Henry

currently on bench:
Matt ryan
CJ Anderson
Todd Gurley
Rob Kelley
Danny Amendola
Delanie Walker

Thanks guys!
