A big game, not a great game as SA rugby are involved.
A big game happens when stakes are high, that the winner takes it all, forcing teams to give their wholesome; committing fully.
WR has yet to understand how to organize a competition as to prevent teams from calculating.
So no surprise, SA and IR are expected to qualify, no competition in the group stage, so are FR and NZ their potential opponents.
FR and NZ play as an opening game to the WC. No stakes attached to the game, it does not decide the qualification and they go blind, not knowing if IR will finish first in their group stage.
Losing or winning does not matter.
Happens IR vs SA rugby, both teams will know the result of NZ vs FR so they will be in a position to calculate what result is the best for them, including a loss.
So big doubts the game is a big game.
