1. Houston Texans Offensive Line
First, a little perspective on this unit. In Superman: The Movie, a teenage Clark Kent punted a football out of his high school stadium. If he played behind this line, it wouldn't matter how far he could kick the ball because he would lead the league in punts blocked. That's how inept this bunch has been since 2002 — just ask quarterback David Carr.

In 2004, the Texans had the third-highest total payroll in the NFL ($97.5 million), and 19 percent of it was devoted to one of the worst offensive lines in football. Carr might have had more success stacking the $12 million between him and the defense and praying that the sight of free money would at least allow him to complete a five-step drop.

After not being able to lure Orlando Pace away from the Rams, the Texans settled on former Saints left tackle, Victor Riley. Left guard Chester Pitts is a penalty machine who led the league with 21 penalties in 2003 and then was tied for second with 14 penalties in 2004. Steve McKinney, Zach Wiegert, and Todd Wade round out a bunch that has given up 33 sacks through six games this season.

Domanick Davis, Vernand Morency, or even Clark Kent won't make much of a difference in the running game as long as there is no one to block for them.
