ALAMEDA — Oakland's Kevin Burnett isn't sure yet what exactly the Raiders will try to do to slow down the unbeaten Kansas City Chiefs this week.
It might not matter what the plan is the way the Chiefs have played while winning their first five games.
That's why even as he buried himself in the film room trying to find an edge, Burnett realized the Raiders will likely have to go off script if they're going to give Kansas City its first loss of the season.
"Nobody's (stopped the Chiefs) so far," Burnett said Thursday. "We're going into uncharted waters. You want to go execute your game plan, but everybody's game plan works on the practice field. It's not until Sunday when you see whether it works or not."
Part of Oakland's offseason defensive makeover, Burnett is sometimes at his best when freelancing on the field.
The ninth-year outside linebacker had 14 tackles in last week's win over San Diego, including a stuff of Chargers running back Danny Woodhead on a fourth-and-goal play from the 1. He also forced a fumble that safety Charles Woodson returned for a touchdown.
Those types of plays have become typical of Burnett this season, his first in Oakland after spending the past two seasons in Miami.
He had 10 tackles and forced a fumble that led to a touchdown in the Raiders' 37-21 loss to the Denver Broncos on Sept. 23.
A week later, when Oakland's defense gave up a 33-yard completion from Washington's Robert Griffin III to tight end Logan Paulsen, Burnett chased Paulsen down from behind and knocked the ball loose for another turnover.
"He plays the game fast and he's instinctive," Raiders coach Dennis Allen said. "When you play this game fast and you play this game instinctively, you're going to make a lot of plays. We're going to continue to put him in a position where he can do that for us."
Burnett was one of the less-heralded offseason signings made by Oakland general manager Reggie McKenzie when the team slashed its payroll and got rid of high-priced, underachieving players such as defensive tackle Richard Seymour and middle linebacker Rolando McClain.
