Futterman, Matthew. 2009. "Behind the NFL's Touchdown Binge As Scoring Soars, One Professor Sees Parallels in Nature: The 'River Basin' Theory." Wall Street Journal (10 September). http://online.wsj.com/page/2_0333-20090910.html
"The NFL has become so fast and efficient that last season, teams each scored 22.03 points per game, the highest since 1967, while all the league's 32 teams combined for 11,279 points -- the most in NFL history."
"Some football thinkers believe these numbers speak to a temporary period of offensive dominance in the NFL -- just one more high point in an endlessly fluctuating historical curve. But if you venture a bit beyond the particulars of football, to the principles of science, there's another argument to be made: that the NFL's high-speed, high-scoring offenses are a reflection of one of the laws of nature—the tendency of all things to evolve toward efficiency.
