As the smoke cleared from a wacky weekend of racing, Jeff Burton continued to remain the class of the Chase field, with the rest of his challengers now looking to play catchup in the second half. Heading into Martinsville, second through seventh in the standings are separated by just over 100 points, so any little bump or bang this weekend could send the standings into a tailspin.

Other than Jeff Gordon's early exit, the Chase picture wasn't altered much until the final 10 laps of the race. That's when all heck broke loose: Jeff Burton had to pit under green with a flat tire, then Jimmie Johnson and Dale Earnhardt Jr. became involved in their infamous last lap crash. In those final 30 miles of racing, the entire points picture changed: Burton went from widening his point lead even more to having it cut down to only six, as by the end of the day, everyone but Gordon had gained on him. A race that had produced clear championship favorites the past two seasons now found itself responsible for tightening the points race.

Jimmie Johnson was blowing by the competition and looked to be heading for a win that could have got him back in the title hunt, but Tony Stewart calmly came in and stole the win away with a little extra fuel. The late race fuel mileage gamble left plenty of other Chasers looking for gas - and answers - at the end of the day, in the midst of several other spinouts and mechanical issues that threatened to doom their title hopes.

After a grueling 400 laps at Dover, which Chase contenders are still hot on the trail of the championship and which ones are chilling out in the back? Read this week's Who's Hot/Who's Not to find out.

With the driver points for the top 10 reset so that everyone was separated by just five points, Sunday's race caused each Chaser to leave in a different position in the point standings than where they started. For some teams, that was good news; they withstood the first test of the championship battle and came out of Sunday's race intact. For others, though, the day turned out to be anything but sunny, and they now find themselves in jeopardy of staring at an empty trophy case far earlier than they should be.

As we head into the first race of the playoffs at Loudon, let's take a look at Who's Hot and Who's Not in the upcoming Chase for the Championship.
