Well they used to say that Union was an Amateur game played by Professionals and League was a Professional game played by Amateurs.
I think Leage sucks these last few decades. It lacks certainty. Is insecure against AFL. Is nothing more than a Tackling game that has nearly more kicking in it than AFL - in fact, most points are scored via a facet of kicking. Rules? What rules? They keep changing more than the bloody fashions of the jerseys. The code is ruled by TV not crowds.
It has forgotten the importance of the Test arena in an effort of jealousy with AFL and aims for the Grand Final level as 'important'.
League has become a gutless and frivolous game that doesn't like the fact that more people attend the Clubs for a good night out rather than the games themselves.
When the Panthers won their 'fairytale' GF - it was because the Leagues CLub 'Panthers' said "You work for us - we don't work for you." and they were right.
Union is far more exciting a game but it is also far more predictable in its traditionalism. Its obvious that the next face of Union here would be to dispense with SA and NZ and just do a national 'Provincial' of all of Australia soon. Pity NRL (National Redneck League) doesn't realise the 'International' arena being left unattended by Union these days. To me League was all about the Kangaroos ...not the Broncos or Storm in this years GF (so obvious!).
Get rid of the video refs and umpires DURING the game. Use em to mark the Ref standards: that is - the more decisions they get right, the more money they make. The more mistakes - the more $ deductions. Chances are that Refs/umpires will improve immensly.
...but hey, 'Sport' is un-orthodox in Australia and South America ...unlike Africa and the Occidental region of the Southern Hemisphere
