Arian Foster, Andre Johnson and Matt Schaub are all top flight fantasy picks. Foster and Johnson are both locked in to go in the first round, and Schaub may be the fourth-to-eighth quarterback off the board depending on who is drafting. No one is going to get a surprise boost from any of these players because you have to take them so high that you count on them to produce for your team.
On the other hand, any offense as high powered as the Texans will have some fallout fantasy points that you can take advantage of—kind of like hanging around a guy that gets all the girls and you are left talking to her cute, but not super hot friend.
Rarely do you see such a disparity between the big three and the other players on the team, but the Texans have been placed in two totally different classes this fantasy season.
