The Red Queen<\/strong><\/p>\n
In evolutionary biology, there\u2019s a concept called the Red Queen Hypothesis. Simply put, it states that groups in a system have to evolve just to keep up with the other components of the system. If not, they irrevocably fall behind. Taken from Lewis Carroll\u2019s Through the Looking Glass<\/a><\/em>, one of the Red Queen\u2019s speeches mentions \u201cit takes all the running you can do, to keep in the same place.\u201d<\/p>\n
The game is faster, too. Walter Payton, perhaps the greatest running back of all time ran a 40-yard-dash in 4.4 seconds in the early 1970s. Comparatively, at the 2010 NFL Combine, six players matched or beat a 4.4, with an additional thirty players running it faster than 4.6 seconds. Furthermore, not only are the individual plays faster, but there are more plays per game than ever<\/a>. In 2007, the average length of a game was 3:02\u201959\u2019\u2019, with an average of 153.1 plays per game. Compare this to a season like 1985<\/a>, with an average of 131 plays per game, or 1960<\/a>, just a hair over 120 plays per game. <\/p>\n
