who to start as my flex rb

Ahmad Bradshaw against KC.  He's been getting carries and with his explosiveness against a shitty KC defense he could easily eclipse 100 yards.

McFadden against a horrid Houston run defense...but Oakland CAN NOT throw the rock so most teams are zeroing in on their run attack.

Ray Rice against Pats defense.  He's been highly productive but obviously the Pats defense is an upgrade over teams they've played so far. 

Thanks for the advice

Just got to worry about the Raiders being down big early and forcing JaMarcus to throw.  Houston might even stack the line and do that from the get go.

does anyone think that michael bush could be a good sleeper this week against houston????
