the top team in SA played against how many NZ teams before the final?
Oh none during the season ...
But remember that the Force and the Brumbies only won 2/4 games against South African opposition (Kings and Jaguars) with all the remaining wins against the other Australian sides.
The Waratahs won 0/4 against South African opposition.
The Rebels won 0.5/4 (Sharks) against South African opposition.
The Reds won 2/4 (Kings and Jaguars) against South African Opposition.
So basically, the top three Australian teams were able to beat the bottom 2 teams in one of the South African conferences.
It also means that of the 21 wins in the conference, 15 were Australian teams playing another Australian team - pretty hard for both teams to lose.
So that is 6.5/20 against South African teams and 0/25 against New Zealand teams.
