The point is Cam, some players have that simple but elegant efficienct capacity that functions at the same personal level what ever level they end up at.
Your Collins, McGoverns, Reids, Kantes at lower levels while not obviously standout world class do, if they are lucky and get in the right team, have within them that capacity to do 'just what they do' no matter how high they go with good players around them.
They (would) fit in a world class teams so seamlessly that they aquire world class and that world class team is often the poorer when they are absent...and if a world class team is poorer without them???
