Need proof that Greg Biffle grabbed Jimmie Johnson by the scruff of his firesuit? Here it is.
Kudos to Johnson for staying incredibly calm in the aftermath. While a kerfluffle would have been intriguing, a la Clint Bowyer and Jeff Gordon at Phoenix last year, Johnson's got much more to worry about than Greg Biffle. And that calmness that Johnson showed in the GIF above is a big reason why he's so successful.
