The Houston Texans are a playoff team for the first time in franchise history which means they should be picking somewhere in the 20s for their first round pick. The Texans defense is already one of the best in the NFL but even with a good defense SB Nation's first mock draft projects the Texans taking a nose tackle:

26. Houston Texans - Dontari Poe, NT, Memphis Tigers
Houston's defense has been great this season. Imagine what they'll do next year with a healthy Mario Williams and 350-pound guy who also possesses the athletic ability of a 300-pound defensive lineman at the nose tackle position.

Over at SB Nation's NFL Draft blog Mocking the Draft, they have the Texans also taking Dontari Poe but at the No. 29 pick:

29. Houston Texans - Dontari Poe, NT, Memphis
The Wade Phillips defense has never really been built around nose tackle, but imagine what a guru like him could do with a player like Poe. Arguably the best nose eligible for the draft, Poe is a hulking figure up front who can occupy blockers and collapse the line. He'd take some pressure of ends J.J. Watt and Antonio Smith, which will allow Houston's linebackers to make even more plays. The biggest beneficiaries of playing with someone like Poe will be Houston's inside linebackers.
