Who should the Houston Texans draft?

They should definately go after a DE with their first pick, if Michael Johnson of Georgia Tech is still available he would be perfect... mario Williams is already a beast on one side, but if they had another monster rusher on the other side, their defense would have a lot less to worry about. Michael Johnson is 6'7, 270 lbs and he runs a 4.7 in the 40 and he would need alot of attention because of his size and play... this would make things easier on the probowl DE on the other side which equals many sack and turnovers for the D. They should go after a big bruiser RB in the second like Gartrell Johnson or Shonne Green to complement the fast and shifty Slaton.
