And then there were 12.  Jamie McMurray, Jimmie Johnson, Paul Menard, and Clint Bowyer, they're gone.  Eliminated.  Out of the Chase.

Kevin Harvick, on the other hand, clinched a spot into the Contender Round in the only way possible: winning the race at Dover.  The reigning champion was on the ropes and responded, and should provide a significant obstacle for the rest of the Chase field moving forward.

Here are three Chase drivers to keep an eye on at Charlotte:

Green Flag - Kevin Harvick

Not even some ill-timed bad luck could keep the defending champ from advancing.  He led 10 laps at Chicago before suffering a tire rub and finishing 42nd.  He bounced back in a big way at New Hampshire by leading 216 laps, but ran out of gas and was relegated to a 21st-place finish.  At Dover, he sealed the deal with 355 laps led for the win.  He now heads to Charlotte to attempt to repeat in the Bank of America 500, a win he used last year to propel himself to the championship.

Yellow Flag - Kyle Busch

Busch has managed to stay relatively hot after a blazing summer, but it hasn't translated into wins.  It probably won't at Charlotte either.  Busch has never won at that track, but does have 10 top-fives in 23 starts there.  Expect him to run up front, but be a little surprised if he visits victory lane.

Red Flag - Dale Earnhardt Jr.

Junior made a heck of a pass to get in front of Jamie McMurray and take the spot he needed to move on to the Contender Round via a tiebreaker over McMurray.  Charlotte is tough for him though.  He's never won a points race there and has just 12 top-10s in 31 starts.  He's probably the only driver in the field that's circling Talladega as a race to which he's looking forward.
