The Chiefs can throw this weekend knowing they will have a home semi no matter what which seems to be the opposite to what a quarter final should mean.
I hadn't thought about the #1 seed potentially throwing their match. But, if I understand this all correctly, this silly concept, and the fact that #2 plays before #1, means that, if the Reds beat the Crusaders (#2) on Friday, then the Chiefs (#1) could throw the match on Saturday against the Blues to guarantee the Crusaders are eliminated, all while knowing that they would be hosting the Reds in the semifinal.
As funny as it would be to see the Evil Empire eliminated that way, it does seem somewhat unsporting.
EDIT: The Chiefs would also be condemning the other semifinal host, i.e., either the Brumbies or Hurricanes, to getting battered by Vern-ball.
