Southerners used to say their two most popular sports were football and spring football.
There was a time when that saying was cited by Northerners as proof of the simplemindedness of Southern sports fans.
Even as that saying has moldered, a new nationwide reality has replaced it. In today's America, there are four seasons: NFL draft season, NFL free agent season, NFL training season and NFL game season. It is never not football season, and the credit for that belongs as much to Ed Sabol and his son, Steve, as anyone.
One form of genius is seeing that which others can't or won't. That the world is round. That the forward pass could become the most reliable way to move a football. That the ugly, bloody, mud-strewn, primordial game of professional football in the early 1960s could be remade into populist opera.
On Monday, Ed Sabol died at the age of 98. His son, Steve, died of brain cancer in 2012.
They, along with former NFL Commissioner Pete Rozelle, were perhaps the first men in America to recognize that professional football could become something more than stop-action rugby. That football could surpass baseball and all other sports to become a year-round national obsession.
One of Sabol's wedding gifts was a $100 gift certificate with which he bought a 16-millimeter camera. He used that device to film everything in his path, and especially Steve's football exploits.
Ed eventually quit his job as a coat salesman for his father-in-law and outbid competitors for the right to shoot the 1962 championship game between the New York Giants and the Green Bay Packers.
