I wouldn't mind seeing the Texans draft this guy but honestly, Seth Wand is going to have one more year of off-season work going into next year and he's going to improve. I think what the Texans really need on their offensive line is another center. You could take most of the pressure Carr has gotten this year away if you could just keep the middle of the o-line from being blown up all the time.
Now if we could get that replacement center (possibly a free agent if one's out there) and then draft Mankins to try and take the job away from Wand then I'd be good with that. Either way the Texans would win. If he can beat out Wand then it's an upgrade, if Wand puts his nose to the grindstone and holds him off then it's an upgrade.
