Look at the work that Melbourne and Cronulla put in after the tackle and compare it to the Dragons.
It's like night and day.

7(5-2) of the 33 penalties were for anything associated to the wrestle/release.
So to the people claiming thats what the crackdown is about, really missed what was on display in regards to the penalties on friday.
2 Grapples at the end of the game cause Storm was pissed.
10 offside penalties
and 4 backchat penalties.
with another 10 to random offsides, running players off the ball, markers not square,
that professional foul & strips.
That compared to todays match which had players warned about offside/Square.
Its pretty clear to see the difference in the officiating between the matches.
Why Sharks V Storm had no warnings with the 10 meters and not square and today it was clear to see/hear they did, you would have to ask Greenberg on why that was the case.
Even with those warnings, you would still have a higher penalty count than most due to the fact its Storm & Sharks.
So its def0 a case of less wanting to blow this whistle and ill discipline on display between Today and Friday.
