McNabb dropped in the pocket, looked downfield and saw a lane open in front of him because the Cowboys secondary were in a a man-to-man coverage. He darted downfield only to feel a tug on his back. It was Roy Williams with another horse collar tackle.
Thankfully McNabb's legs didn't get caught under Williams' body, so he wasn't injured. You could tell by the way Donovan jumped up and started protesting, that he knew he had come close to being injured again. The flags came from all over. Williams had been busted again.
After viewing the tape, finally the NFL is really coming down on Dallas safety Williams for his horse collar tackling technique. They tried fining him, but that didn't work, so now they're going to suspend for a game.
Remember he was the guy who injured then Eagles wide receiver during the Birds Super Bowl year. It took Owens off the field until the Super Bowl game against the Patriots. It wasn't Roy's only victim. He's put four or five players on Injured Reserve with his taxing technique.
Williams has been utilizing this technique throughout his entire career. The NFL has fined him numerous times but that didn't slow him when it came to grabbing a player by the back of his shoulder pads and pulling him down while sliding down on the back of his legs. Now they're going to suspend him for a game.
