Football is a constantly evolving game, in all facets. College football is nearly unrecognizable 60 years ago compared to the modern day game, in pretty much every imaginable way. Massive changes in the way programs recruit, the way coaches manage development, and even in the way the game is played on the field, have led to an entirely different game from the origins of college football.
Athletes and coaches, thanks in large part to exercise and recruiting advancements, are bigger, faster, stronger, and smarter than ever, and in no place is that more evident than the way offense is played in modern day football.
