The big difference between the 70’s 80’s and today is predictability.
You know the drum , tackle 1 hit it up, tackle 2 ditto, tackle 3 ditto, tackle 4 ditto, and finally on the last hoist it either in the air if close enough or into the corner without in going out for field position.
And then occasionally you attack the line and mostly dribble the ball through for a repeat set, because you then know the opposition will give away a penalty ( or two) and you’ll get 3 or 4 sets at the line and probably score with a wide running forward powering over the line.
Kick off, repeat.
Kick off, repeat.
Kick off, repeat.
And the main thing that decides the game, penalties , how many, when and where given.
There’s virtually zero individual brilliance nor is it encouraged.
Oh sure some still display it occasionally but today’s “ game” is more like tactical warfare than the beautiful game it was 40 years ago.
