If this was already posted I do apologize: NFL Draft Countdown Mock Draft 13. Houston Texans: Cadillac Williams, RB, Auburn Every year it seems as though a player drops further than he was originally expected to and I am becoming more and more convinced that a running back could very well fall into the Texans laps here. If this scenario does play out with either Cadillac or Cedric Benson word has it Houston would be more than happy to capitalize on the stroke of luck and upgrade their rushing attack. Carnell Williams is an elite running back prospect and while he doesn't have tremendous size he is a fast, explosive athlete who is a threat to take it the distance at any time. It is really a testament to what a good pure runner Williams is that he is considered such a top prospect despite not having the ideal size or speed you look for. In fact, Caddy has been moving up as of late and is being considered by Chicago at #4, Tampa Bay at #5, and Minnesota at #7 as well. Houston is also in the market for another top wideout with speed to team with Andre Johnson so if all three of the running backs are off the board this pick could very well be Troy Williamson. The Texans have also been longing to bring in a franchise left tackle which they basically admitted with their failed attempt to trade for Orlando Pace so if Alex Barron is still available he would be a serious consideration as well. This is actually a team in a pretty good position and they can afford to wait and see if a top prospect falls to them, and the odds seem to favor that happening right now. 47. Houston Texans: Justin Tuck, DE-OLB, Notre Dame Has a shot at the first round but if still available here he would fill a major need at outside linebacker. 73. Houston Texans (f/DAL): Roydell Williams, WR, Tulane They are itching to add another top young wideout to compliment Andre Johnson and this guy is very underrated. 78. Houston Texans: Ronald Fields, DT, Mississippi St. Seth Payne is coming off an injury and depth is needed so this massive nose tackle would be a nice fit here.
