This seems to confirm that SA will move away from SuperRugby - and not pursue legal proceedings- or seek another arrangement. There was some dispute that contract ran longer, but SA must not be pursuing it.
Australia seemed to prefer a smaller tournament that has about 2 teams each following a separate local derby knock out as round 1. So that looks like it is history as well. New Zealand only want about 3Australian teams- to ensure they are competitive.
Pro14 is a step-down, given that many of the best Northern Hemisphere teams field B-team players, and save the best ones for the European cup- and Test rugby. Not sure how many games each player has per season.
The skills of the New Zealand backline wil l be missed. Their forward linking, trucking and fetching skills too.
Not sure what happened with Australia, but their forwards do not pull their weight. Their backs lack possession to be consistent week on week.
