Leaders' blunders wreak havoc on Sam's Town 300

It doesn't look like anyone wants to win the Sam's Town 300 as the past four leader shave had some type of mistake that took them out of contention.

The latest was Brian Vickers, whose crew on the No. 32 Dollar General Toyota missed a lug nut on the right front wheel. NASCAR caught the mistake and penalized Vickers with a pass thru penalty to get the lug nut back on.

Oh my God, the leader of the race, David Ragan, just spun coming onto pit road and slammed into the Turn 4 wall.

I was just about to write that Carl Edwards was penalized for speeding on pit road and Brendam Gaughan spun turning onto pit road. We're back to 10 cars on the lead lap and somehow, Greg Biffle has found his was back to the front of the field. But, at this point, is it worth leading the race?
