Need help with Flex spot

[subguy89]

Hello,
I am in a standard 10 team league. Below is my lineup for this week. I am not sure about the WR spots.

QB Shaub @ Ind
RB C. Johnson @ Oak
RB R. Grant @ PHI
WR R. Wayne @ Hou
WR W. Welker @ Cin
RB/WR S. Smith (NYG) @ Car
TE J. Witten @ Was

On the bench;
WR Malcom Floyd @ KC
WR Mike Wallace @ Atl

I am thinking about taking out S. Smith and starting M. Floyd. Please help. WHIR, Thanks in advance.

Pretty close plays here. I would go Floyd, simply because he has the better matchup.

I think that I'd go Floyd on this on. KC will give up yards left and right and Floyd should see a good part of them.
