Fantasy Football: Who should I start?

[showtimesam]

Ok, I'm in a twelve man league and I have all my starters set except for the flex position. I have three candidates that I'm debating for that spot:

Lendale White: He's been getting 20 carries a game for usually around 60 yards and he's often been good for a touchdown. Plus the Houston run defense has been pretty terrible.

Kevin Jones: He's the starter now, and yards should be easy to come by on the ground against tampa's cover 2 defense. He's also their goal line back, and with Detroit being at home they should move the ball down the field pretty well. He's also most likely good for at least 4 or 5 catches out of the backfield.

Roddy White: White has been a very steady 4 catches 60 yards type performer. This week they are playing the pathetic New Orleans pass defense and White has a good chance of going off for 5 plus catches 60 or 70 yards and a touchdown.

Between the three, who do you think I should go with?
I've been searching Yahoo, Foxsports, and Cbssportsline and they seem to be pretty even in their expectations this week.
Any help would be appreciated, thank you!
