King described the efforts of the less experienced forwards – Josh Starling, Dunamis Lui, James Hasson and Jesse Sene-Lefao – as "enormous".
"I thought they were great for us; when they got an opportunity off the bench or if they started, they just did their job I thought," King said on Tuesday, in the wake of Friday's clash in Gosford.

King played strongly in his first game in 10 months and engaged in a running battle with the Rabbitohs' three enormous Burgess brothers, including exchanging verbals with Sam and a couple of monster hits with Luke. Yet he said he still had some work to do ahead of the clash with the Eels at Brookvale on Sunday.
"I took a little bit of confidence [out of the Souths game], knowing that I can still play, to get back out on the park and make a few tackles and a few hit-ups but I was pretty rusty and my lungs weren't that good and my defence probably wasn't up to scratch," he said.
"I took a few things out of it but [I'm] just trying to find my groove again."
Lawrence was of the view the new-look pack made a statement that should silence the doubters, and welcomed the return of King.
"[There are] a few new guys in the side that need to make a bit of a statement and I think they're doing well," he said.
"I think the guys came off our bench really well. It's good to have Jason King back, he had a good stint, he aimed up a bit. It's something we hold a bit of pride about and I think you're right [we did make a statement]."
