The Texans are considering whether to draft a quarterback with the top overall pick of the NFL draft.

They have also met privately with Louisville quarterback Teddy Bridgewater.

The Texans could also go with ultra-athletic South Carolina defensive end Jadaveon Clowney.

The Texans traded former starting quarterback Matt Schaub to the Oakland Raiders.
