How has technology changed the rules in soccer?

Answer 1

football in the 1980's was less uhm athletic now in modern days sports officials have "Instant Replays" and all the players have improved training with timers and those things that shoot footballs.That all makes the players faster more athletic to make the game of football less run up the gut but pass and counters.

Answer 2

Sadly, it hasn't at all, because soccer (via FIFA) is ruled by a senile prepotent man named Sepp Blatter, who would rather spend his time discussing suspenders (i'm not making that up) than consider technological advances to the most important sport on Earth.
