2 things:
Just before the Penrith try they took the quick tap on their 20m line after Robson kicked dead. The rule is it is only the person that retrieves the ball who is allowed to run it back for the quick tap. The guy passed it 10metres out to the 20m line for Kingston to tap it and pass it on. They made the break because the Sharks were not back. How is that allowed.
Secondly, on Best's break, he passed it and Walsh knocked it down. The ball was picked up by a Panther who was atleast 5m infront of Walsh... How is that not offside?
