Yes there were shit calls on both sides but there's no doubt Penrith got more benefit.
They benefitted more by missing out on a one-man advantage?
I have no love for either side but I don't agree. People get too caught up in the after-effects of the decisions IMO. The Roosters gave up a try after the dangerous tackle call so it sticks out, but unless the referee is literally awarding an incorrect try that's not on the referee. The decision was wrong and it gave the Panthers an extra opportunity to score but the Roosters could have defended it, even Karenson said as much.
The focus needs to be on the decisions in isolation, otherwise the refs won't be held accountable IMO. Because it's so easy to write it off if you start blaming the ref for events in the game that they don't control.
IMO the missed shoulder charge was an equally poor decision but it's not something people think is obvious if it doesn't "lead directly" to something detrimental to the Panthers.
