off-sides rules are the reason everyone complains when a B-Ball player doesnt hustle back and gets a cheap layup.
I get the people who love soccer in its current form. Still other sports have changed drastically over the years. subs/timing/pt values/pitches/ot rules/etc . what major rules have changed in the last 80 yrs in soccer?
I can do it since the 90s:
The offsides rule. 1990.
The backpass rule. 1992.
Introduction of VAR. 2018.
DOGSO (or the professional foul). Many times in the period you referenced, but most recently in 2017.
Change in substitution laws, goalkeepers (2+1). 1994.
Change in substitution laws, all players (3). 1995.
Timing changes for hydration. 2016.
Timing of Halftime. 1995.
Change in substitution laws (from 3 to 7 as long as agreed upon prior to the match -- later reduced to a maximum of 6 in the 2000's).
Several safety related changes, including tackles from behind.
About five changes to overtime rules (golden goal, silver goal, 15+15, subsitution changes, etc)
Methods of scoring, including away goals, throughout the period you referenced.
But if you really don't believe there have been any changes to the game in the last 80 years, go to 1:40 of this video and realize that the play was completely legal and the goal counted. Today it would be an obvious sending off.
I think you are trying to talk about something you are not really educated about.
