I don't see the Texans going NT in the 1st round, they picked DJ Reader in the last draft and I think he's the future of the position. The Texans may pick a lower round NT for depth though. I'm hoping we take an OT in the first if one of the few good ones somehow falls to us, it's not a good year for O-line prospects, or possibly a TE since it's a good TE draft. A Safety in the 1st isn't out of the question either, good year for Safeties and CB's.
Of course, at this point in time, no one knows how things will be come draft time, but I really have to believe, at some point, the Texans have to upgrade their O-line and I hope they start with their 1st pick. I wouldn't mind getting Lotulelei if getting a DT was all that we needed. But, the reality of the situation that the Texans are in is that they are severely lacking in talent on their O-line, and if they want to be a top team competing for SB's they need to upgrade that talent. And, if this is a bad year for O-linemen in the Draft like many are saying it will be, then all the more reason to get an OT in the 1st round and lock in one of top ones in the Draft.
