It didn't decide the game. That's your opinion. My opinion is different.
If Jorge catches the ball and Parker doesn't give a penalty away on their try line - maybe we win - maybe we don't.
The rules are the rules. Jurbo broke the rules by pulling a players jersey from behind. Irrespective of whether the refs used their "feel for the game" in this instance, Jurbo still broke the rules so as I said - I'm ok with a 50/50 penalty or sin bin.
As I stated earlier, the refs have been given too much license to get a "feel for the game". This results in inconsistency. The NRL went this way because when they tried to enforce the rules - it became a penaltyathon. The rules are there to be followed, it's the refs interpretation and license to "feel" a game that's destroying it.
If they ditched their "feel for the game" last night and reviewed Jurbos situation, I believe he still gets 10 in the bin because it's a professional foul to pull/push a running player from behind. Shoulder to shoulder only.
In my opinion, the moment the game decided to not enforce rules (due to too many penalties and the related media hysteria that followed) and allow ref discretion in calling a game is the moment it went pear shaped. I don't think you will ever get consistency back until the NRL enforces their own rules.
