In the National Football League the rules allow for forward passes and rushing for the purpose of advancing the ball and getting that new set of downs. Players in 2013 are creative though as they weren't so much in the 1960s when I first began watching the National Football League on television. Basic rules are forever, mostly, or you're inventing a new sport.
The players today, in 2013, are without a doubt bigger and stronger at every position so if you can't run someone over then fly over him. It seems to be a case of self-preservation to not take on huge defensive players if you don't need to.
In the 1960s the Packers got first downs with that famous sweep; passing had its Starr, Bart Starr, but he really didn't pass much at all by today's standards. No one passed much like today; even teams like the San Diego Charger's (of the 1960s) numbers aren't really so remarkable if compared to NFL numbers in 2013. Players didn't seem to go airborne much in those years where slow (which reflected strength I suppose) was respected and dazzle as in flying high was, arguably, not fashionable or even, dare I say, dignified. Look back at the sports footage of the 60s: it was a slower and more measured time for everything.
Am I wrong?
Going airborne is something I looked into; in the pursuit of this angle on the NFL which the game photos revealed I've collected some photos from NFL games in 2013. Going airborne is the final frontier in gaining yards: going for that crucial first down or touchdown.
