Be sure Driver is playing. If not, feel good about NYG Smith as your WR3.
The only other concern, like you said, is RB.
Get Addai out of there. The Texans have improved their defense against the run, and Donald Brown should be back. Besides, Addai ws extremely average as the feature back last week.
I love Ronnie Brown in any given week, and slightly behind him is the sensational Ray Rice. I think the Patriots can be run on, and I'd say the same for Cincy. But Brown is so much more versatile, you just can't sit the guy right now.
I vote to plug Brown in there, and roll with Steve Smith, but only if DD sits out against TB.
