People are nostalgically hoping the game reverts back to the unstructured randomness that was the game in the 70s.
It's never going to happen, the game is too structured, to coached and too professional for this ever come back.
People have got it into their heads that the interchange is the sole reason that we don't have flowing football like they had back in the 70s. While they did have structures, game plan's etc back in those days it was no where near the level of today. The game has evolved in all areas since the 70s, we have stronger defensive patterns, better strength and conditioning, bigger outside backs, detailed match analysis, bloody wrestling ... the list goes on, and to think that a change in the interchange rules will undo all the work in all those areas is a bit naive.
People say they want different body sizes in rugby league, well look up the wide shots of teams doing the national anthems in big games, there is already a huge variety in our game.
People want to bring back the bring back the smaller players in our game, but forget that guys like Thurston, cronk, hunt, milford, reynolds, keary, luke, Segaryo are all killing it at the moment
People want the talented players to thrive but they are, thurston, inglis, slater, Johnson are as talented as any players from any other era, but the game is now to professional and a guy like Sandow shows that talent can only get you so far
