It will be interesting; it always is. Under 20s hardly ever play their "best side" anyway; so we'll have to wait for the money games at the end of the tournament to see who is their best for the opponent they have on that day.
The match lists in the tournament are always a compromise between using all their squad to have players fresh, who their opponents are, who plays best with whom, who should be played as much as he can be, and who he will, or won't, be playing with.
A player's abilitity to play with rugby strangers, back up up with a short turnaround (three games in eight days in pool matches) and play in different positions would have been a part of the selection of the squad in the first place.
As for a Super rating — if Burton had been a Sydney boy and Stewart from Perth … you know what I mean.
But this is a Randwick thread and I'll leave it at that.
