HELP Too many good matchups this week- Start em Sit em

So I have:

Lamar Miller (vs CLE) ???
Alvin Kamara (vs DET)
Buck Allen (vs CHI)
Duke Johnson (vs HOU)
Ty Montgomery (benched)

Alshon Jeffery (@ CAR) ???
Devin Funchess (vs PHI)
Emmanuel Sanders (vs NYG) ???
Rishard Matthews (vs IND)
Willie Snead (benched)

I need 2 RB’s, 2 WR’s, and a FLEX. Need some advice because I am lost on who to start and I feel like my typical starters might even be better on my bench this week
