Dockett giving Cardinals' defense an edge

Posted by ESPN.com's Mike Sando

TAMPA, Fla. -- Pete Prisco's profile of Cardinals defensive tackle Darnell Dockett gives an idea what Dockett has gone through in getting to this level. We also get a better idea why Dockett plays with such an edge, and why he responds so well amid skepticism.

Dockett: "I play with passion and emotion because this game wasn't handed to me. I wasn't one of those silver-spooned kids who has been playing since he was 5 years old. I had the same high school cleats for three years and I would have had them for a fourth if my big toe wasn't about to burst out of them. I learned to move on from everything in life and to take advantage of every opportunity that I got."

The hit Dockett put on 49ers fullback Zak Keasey in the 2008 season opener was one of the more violent hits you'll see near the line of scrimmage (as opposed to the open field, where collisions tend to be more spectacular).

Dockett's best game this season might have come during a Week 6 victory over the Cowboys. Dallas could not block him. Dockett struck again during the wild-card round when he drove Falcons guard Harvey Dahl into the backfield quickly enough to disrupt a handoff, setting up a fumble return for a touchdown.
