Rassie vs. Rennie: Unwanted sideshow or just what rugby needs?

The coaching rivalry between All Blacks coach Dave Rennie and Springboks director of rugby Rassie Erasmus has become a notable sideshow to the Greatest Rivalry series between New Zealand and South Africa, which is currently tied at 1-1. Rennie, an experienced coach who has led teams across New Zealand, Australia, Scotland, and Japan, has publicly engaged in tactical exchanges with Erasmus, showing no signs of backing down. Opinions are divided on whether the coaching banter enhances or detracts from the on-field series.
