Need some advice on RB starts: SJax/DMcFad/RonnieB

[jtdragon]

Need to start two from this list (no flex in my league, not PPR, standard scoring):

Ronnie Brown (vs Buf)
Steven Jackson (at SF)
Darren McFadden (at Hou)
Ray Rice (at NE)
Reggie Bush (vs NYJ)
Knowshon Moreno (vs Dal)

Any advice is much appreciated. I'm planning to go with Ronnie Brown and S Jax, but after seeing what the SF defense did to Adrian Peterson, I'm starting to lean towards McFadden and his juicy matchup against that porous Houston defense. Help!
