I wouldn't mind seeing 'real' scrums. Not the RU style but at least not a lean in.
Also, the NRL needs to challenge clubs to get out of this mindset of dull footy. There are so many rules to exploit, but a generation of coaches like Sheens, Smith, Bennett and Gould wanted low-percentage plays, minimal errors and to coached a lot of the 'instinct' and had rule change put in to suck the life out of the game. If something was in the game that made it exciting and against the grain, you can be sure they found a way to nullify it or have it nullified in a negative way. And Sheens, Smith and Bennett have begat us the next generation of coaches who are too scared to allow flair to rule because if they lose in an exciting way, it's their head on the chopping block.
I'm sorry I'm on a soap box but it really annoys me that tweaks aren't made to better the game, to make it positive. Hell, I can distinctly remember the last time a deep set, long sweeping back line was used and it was Penrith a couple of years ago and they scored because the defence had NFI how to defend against depth and bodies in motion.
Come on NRL! Excite us again and feck off the wrestle and 5 up and kick.
