Thinkin’ Out Loud: 2012 Pure Michigan 400 at Michigan

Jimmie Johnson had the dominant car once Mark Martin was speared by the pit wall opening in a scary, mid-race crash. But as J.J. was strolling to what would have been his series-leading fourth victory, a valve spring failed with less than 15 miles left to run. That handed Greg Biffle Christmas in August, gift-wrapping him a second victory after a green-white-checkered finish and a pesky push from Michigan native Brad Keselowski.
