If they got hold of them?Only if they got hold of them. Which they wouldnt very often. There are plenty in the modern game who could punch on no worries.
Imagine a modern winger setting course for the corner v an old school winger. They’d score every single time. The old school defensive tactic of having the lock sweeping would be ripped to pieces by modern halves.
It would be a slaughter.
It was the 3m rule back then…pretty hard not to get hold of someone.
Don’t forget contested scrums too… and unlimited tackles.
Plus no replacements running on and off.
Modern players would never win a scrum to have the ball.
As for wingers setting sail for the line?
There’s no one playing today as fast as a bloke like Ken Irvine… they would never have caught him.
Plus no try if you touch the corner post.
Impossible to compare the two games.
