Agree with all posts, just a point, I hope he never joins the " wear & tear, injuries it's your fault brigade " after retirement etc !
I have listened & spoke to many ex players who not only have ongoing injury & pains but to on to say they have no regrets &
Would do it all again having enjoyed their days + they blame no one, they knew the risks eg, from other players they knew !
However, New links are found eg, head injuries, & damaged nerves etc which can lead to certain cases of extreme deterioration.
That/those issues were not previously known ! ????
The way forward may be screening & insurance for end of playing days ????? Or the game may go to touch & pass ???
