No game quite gauges the form of the two teams than playing teams who consistenly end up a rank above you below you or even 2 ranks! Frankly that top 6 even 8 in the year before a Rugby World Cup is kinda the start of the whitling down of who will be in the semi-finals… even nearly definitely the quarter-finals!
Will there be upsets! Its definitely possible… just think of South Africa v Japan in the 2019 games… so Zinzan Brooke who scored one of the most famour drop goals in rugby history against England who also scored a kinda really really famous drop goal definitely has shown his continued enthusiasm for the great sport of rugby union.
In a recent interview he covers a lot… players, top players, the up coming England v New Zealand Game… world cup semi-finals… can New Zealand win with this team and more…
