Funny you say that,
The way the game is being ruled now the commentators don't know the laws but that's not the problem, the fans don't know the laws, neither do the players and that is a problem.
What's ok one week is not the next, the scrums and breakdowns and even Mauls are a black hole where anything could happen
I love rugby, but I look at league now and I can watch it and the vast majority of the time games the refs are not a factor, right now Rugby Union seems to be totally dominated by the refs and what they decide to see or ignore and which direction they point their arm.
