Sadly this magnificent event in the 1989 Grand Final would not occur now ......Brereton would have been concussioned out by Doctors ...the same Doctors who passed him fit to continue in 1989
So has medicine changed ....were doctors closing their eyes to concussion, due to team bias .....no doubt yes
It’s both. Players definitely had more power back then to make a call on whether they can play on. Medicine is a constantly changing science. Our “best approach” is in constant mode of updating.
