Dallas Cowboys at San Diego Chargers | Scouting report The Chargers, in their first year playing the 3-4 scheme, finished 10th in defense last season and sixth against the run. It sure helps to have a nose tackle (Jamal Williams) who not only occupies blockers, but can penetrate the backfield to blow up running plays. San Diego defensive coordinator Wade Phillips knows 3-4 defenses better than most and finds a simple, fun way to play it. Dallas coach Bill Parcells is making the same transition and he did a good job in finding young players to execute it. The draft class that includes DeMarcus Ware, Marcus Spears, Chris Canty and Kevin Burnett is his best since the four aces he drafted with first-round picks when he was with the Jets. Veteran newcomer Anthony Henry is better than billed at cornerback. The defense should be good, and much better than 20th against the run, as it was in 2004. The big question is how the offense comes together. Drew Bledsoe has reunited with Parcells and is playing with passion. He's still bitter the Patriots and Bills gave up on him, and sick of the comments that he doesn't get rid of the ball quickly.
