The Las Vegas Raiders hired Gus Bradley as their new defensive coordinator Tuesday with the task of turning around one of the league's worst units.

Coach Jon Gruden decided to bring on the experienced Bradley to fill the role Paul Guenther had for the first two-plus seasons on his staff before being fired in December.

"This is an exciting defense to play and I would say that the players will be very excited to be a part of it because they know that they're going to have the ability to play fast," Bradley said. "I think our job as coaches is really to evaluate the players and put them in position to where they can make plays."
