The Texans return their offensive line intact from last season, so Caldwell should be the top reserve on the interior. He figures to take over for center Chris Myers by 2011. Source: Houston Chronicle
Texans agreed to terms with fifth-round TE James Casey on a four-year contract.
The Texans have talked about using Casey at several positions, but he's likely to be limited to special teams as a rookie. He's fourth on the depth chart at tight end and will need to work on his blocking to move up. Ultra-productive at Rice, Casey could be Owen Daniels' successor if contract problems can't be ironed out next season. Source: Houston Chronicle

Anyway, I like that they both got 4 year deals!
