How Does One "Football"?

Got a post suggestion from a friend and I love the idea. He noted that with many new subscribers on the site, perhaps I should circle back on "Footballing." I use the term all the time, and I've written about the concept for years, but not everyone fully understands what I mean.

This is the weekly NERDstats column, so let's begin with the I-N-I and then we'll get to the Footballing.
