Just about every Mock Draft we've seen has the Texans looking for help on the defensive side, particularly along the front seven where they will be transitioning to a new defensive scheme. Defensive end happens to be a position of strength in this draft, and it could be something the Texans target.
In the latest version of their 2011 NFL Mock Draft, the fellas over at SB Nation have the Texans taking Missouri Defensive End Aldon Smith. Here is their rationale.
Some question whether or not Smith is capable of playing 3-4 outside linebacker. In Wade Phillips' one-gap system, his natural athleticism and pass rushing ability would be at the forefront.
Smith measured out with pretty good size for a 3-4 outside linebacker at the NFL Combine, and might be a little bit too small to play 4-3 defensive end like he was in College. But an undersized defensive end would make for an excellent pass rushing outside linebacker for the Texans. He is a bit of a project, but he has the potential to develop into an excellent player.
