The reason they were brought in, makes sense, and it's why PVL and his defenders will constantly go back to, do you remember what the game was before they came in.
Their application, is what is shit. You can barely find out what they are for, for statistic purposes they count each set restart as equal, but in reality they couldn't be further from equal. A tackle one set restart coming out of your end on the 23m mark, cannot be viewed the same as a 4th tackle set restart 10m out, yet when they review the nature of an infringement count, and whether it was even or not, these 2 set restarts are valued the same. They are not.
I watch most games, but as above, I support the Broncos, not really the game. If I wasn't interested in the fantasy comps side of things, or same game multi's, I'd probably only watch Broncos.
I don't think they can or know how to fix the ruck/10m, and until they go back to 2 referee's, so it can all actually be officiated properly, I don't think anything will change whilst set restarts are as they are. The policing of the ruck is different game to game, team to team depending on momentum and other factors, so to me, they as they are right now are helping to create this feeling about the game.
I'll die on the hill that I think 2 refs on field is the way forward to actually police the ruck and 10m properly.
