Help me decide on a FLEX this week! .5 ppr

[sirchadwick1]

I'm rolling w/ Forte and J-Stew for sure this week. But I cannot decide who is best at FLEX for week 3.
Here are my options:

M. Floyd @ SEA
Sproles @ SEA
S. Greene @ MIA
F. Jones @ HOU
M. Williams TB (home) v. PIT

Everyone is saying this is Greene's breakout week, I'm just not so sure.
Sproles looks like he's in a good spot to get some attention w/ Mathews out.
Felix is awesome, but DAL just hasn't gotten it together yet.
I like Floyd, but feel more confident putting a RB at flex.
Don't like Williams against PIT's secondary.

Thx for the help guys!
