I'm not a RL hater at all. I just felt the need to say that in my opinion,it's the same outcome nearly every time. Admittedly i know little about the tactics of RL but i have over the years seen England's hopes bulled up,knowing only too well that they won't win the RLWC. In short. I know zilch about how RL's played but i'm observant about the outcome of these events. If someone was to say to me "bet your house on Australia winning the next RLWC" and the odds were very good,i'd take up the offer.
Your first post did seem to poor scorn on what was in many ways a successful World Cup for a sport that is struggling to grow outside the heart lands. That said there's lots to be positive about, tonga and Fiji were very strong, players opting to play for their countries rather than taking up residency rules to play for NZ or Austrialia.
The Australian league, the NRL, is very strong, one of the reasons they dominate RL and RU is currently struggling for the most talented atheletes. NRL I believe have just signed a billion dollar TV deal, no idea of the exchange rate but it sounds a lot to me, whether true or not there's a lot of money in the game over there. The league attracts the best players from U.K. And particularly the south sea islands, meaning the strength of those countries is improving and will make a stronger competition next time round. Unfair to compare to RUWC and particularly the football WC as they are played wider, but RL is growing. In the northern hemisphere France now has two clubs in the U.K. League along with Toronto who have amazed everyone with their ability to finance a club and pay for everyone's travel, New York are rumoured to be the next. So lots to be excited about for RL
Back to your original point, yes Aus are the best but it certainly wasn't a forgone conclusion they won. 2021 WC is growing to 16 teams and lots are bound to be stronger, maybe Aus will win again, but I'm sure it will be a great tournament, just sit back, enjoy the feats of these super human atheletes and give credit were its due.
