DOVER, Del. – Matt Kenseth has NASCAR Chase for the Sprint Cup Championship perfection. Kyle Busch nailed the runner-up finishes. And no driver can touch the championship pedigree of Jimmie Johnson.

Led by Kenseth, the top three drivers in the 13-driver, 10-race Chase have started to separate themselves from the rest of the field with eight races remaining. But is the contender list set entering the AAA 400 on Sunday?

Fifth-place Greg Biffle of Vancouver, Wash., said, “I can’t imagine, with eight races to go, that somebody would be willing to say, ‘Oh, this is a three-man race.’ ”

Biffle won the first two Chase races in 2008 and ended up finishing third.

The consistent Biffle was second in 2002, seventh in 2009, sixth in 2010 and fifth last year. But when it comes to true title contenders, the driver of the No. 16 Ford’s name is seldom tossed around in the same category with Johnson or Kenseth or Kyle Busch.

“Am I surprised they’re not talking about the 16? Not really, because we tend to slide a little bit under the radar all the time anyway,” Biffle said. “It doesn’t bother me. It gives you motivation to do well and compete every week and try to get what you can. If you’re winning races or you win the championship, they have to talk about you, so put yourself in that position.”


Joey Logano won the 5-Hour Energy 200 Nationwide Series race in Dover, but his Ford flunked postrace inspection because both sides of the front were too low.

Penalties, if any, will be announced by NASCAR this week.
