Sounds simple: One blown engine and a top-five finish can change the points lead in one lap. Put simply, Biffle can finish 39 positions higher than Johnson and catch him in one race. Those are the possibilities. The probabilities are something different if one looks back in time.
The last time anybody finished 39 positions ahead of Johnson was at Charlotte earlier this year, coincidentally also the last time Johnson blew a motor. It was the only blown engine the No. 48 car has had since the fall 2005 race at Bristol -- 116 races.
But it all goes back to the margin. No driver in the modern era has overcome a greater margin with four races to go and win the championship.
