Fun Fantasy question???

[Bo$$ Bet$]

Alright pretty much I just wanna get opinions on who I should start tomorrow

I get 2 RB 2 WR 1RB/WR here's what I got:

A. Peterson
R. Mendenhall
M. Forte
D. McFadden
L. Tomlinson
J. Harrison

C. Johnson
H. Ward
S. Smith / CAR

I'm thinkin:
2 RB
Peterson
Mendenhall

2 WR
C. Johnson
S. Smith / CAR

This is where idk
1 RB/WR
Forte
McFadden
Or
H. Ward?
