Texans DE Mario Williams, who has only three sacks in seven games, continues to be affected by a bruised shoulder that hampers some of his pass rush moves, including those requiring strength and have forced him to be more of a speed rusher. Despite the injury, Williams is playing the run better than any time in his four-year career. He ranks fourth on the team behind three linebackers with 24 tackles and his 20 unassisted tackles rank third. Source: FOXSports.com
Bullcrap. 3 sacks in 7 games are definite sign of slowing down and he would only have 2 if he if wasn't for him being unblocked on that play in the SF game.
