On another forum, I, amongst other posters, noted that the way in which the game is played and reffed is going to, and has, led to more injuries day to day and probably the risk of longer term harm to players.
This came out of a discussion about the ruck and the way it is played in the Prem mostly, as compared to the ways its played, especially, in Mitre 10 games and how that enforced fast ball meant a better game to watch and one which encouraged a different fitness and reduced impacts on players at the breakdown
I think rugby does have a general injury/way the game is played problem, especially at top level, but not exclusively.
Also - for me - the modern game has shown to me, anyway, that the Laws and the physical nature of the modern pro game don't line up well. RU is (for me...) more of a fit PE teacher game - with current Laws and application and the power and size of so many modern players has reduced space and increased impacts. The enforcement of the Laws like in Mitre 10, may reverse this a little - or else - top level rugby could become unattractive
I've found I've liked more of the games in the Prem with the 6Ns squads off on international duty.
