The Roosters dominated the Storm in the first half, establishing an 18-0 lead, and then held on to claim an impressive victory.

"It’s so good, I can’t talk," Cordner told Channel Nine.

"We started so good that first half. I don’t think we’ve played a better half of footy. We just hung in there in the second half. They had a bit of the run as we expected them to. But how goods this? It's why we play footy, it’s the best ever."

Cordner revealed halfback Cronk courageously played the grand final with a broken scapula.

"We knew Coops was touch and go there," he said.

"He pulled through. We had to make up a game plan where we protected him as much as possible. We executed that, but we knew defence was going to win it. To put in a performance like that on the biggest stage is unbelievable.

"Just him being there, him at 30%. We want him on the field. He actually broke his scapula [against Souths], so that’s a big performance from Coops. That will go down in history."
