I started playing rugby when I was about 12, so mid 70’s when Wales were sublime. Our coach was a Welshman whom waxed lyrical about the Welsh team . He also had a Philips video player so played us recordings ( which I think he got from a friend at the BBC) of Wales when training was called off...
Sadly very little video of him playing but what there is shows what a majestic fly half he was. He didn’t so much run as glide, he made it look effort less.
