Winning vs. Consistency: The Delicate Balance of the NASCAR Playoffs

The NASCAR playoffs determine the season’s champion. Is the champion the guy who wins the most races? Or the guy who runs up front the most?

Manufacturers and teams were consulted and they all feel that their opinions mattered and were taken into consideration.

One of the commentators after the final race in Homestead mentioned that Jimmie Johnson should be happy he finished in third because it allows him to avoid the “dreaded second-place curse”.
Anytime someone says something like that, it makes me wonder whether there really is a curse, or whether that person had just been talking to Carl Edwards. So I analyzed a little data and guess what… there really IS a second place curse. […]
