On a weekend when, once again, rain changed the game, in the end, the real game changer was Kurt Busch’s blown tire just before the white flag. At first, many questioned the caution as it appeared that Busch had gotten his slowing car onto the apron, but television replays showed that the left rear tire on the No. 41 came apart, shredding the car’s quarterpanel. Debris quickly spewed all over the asphalt, and some made its way onto the racing surface. The caution was a good call, and it set up a green-white-checkered run that a year or two ago would have been much different.
