The Demons bull has launched into Brownlow contention in 2020 after working on his aerobic range, which has allowed Petracca to play a majority of his time in the midfield and then rest as a forward.
Zurhaar, a similar frame and role player to a younger Petracca, was headlined as one Kangaroos player King would like to see mimic the shape and capabilities of Petracca in the upcoming off-season.
“Not just Cam Zurhaar. The question for young players is ‘how good can I be?’ A lot of young players just wait for 60 or 80 games for the penny to drop. I think they are waiting for nothing,” he explained on Fox Footy’s First Crack.
“There’s no reason to wait. Look at Christian Petracca and what he has been able to physically do over the last 12 months. He’s made a decision to consciously change his whole lifestyle and look at the benefits.
“Just in body shape you can see he is a man now, he has dedicated his life to become the full package. I don’t think he would’ve expected to have the 2020 he has had.
“Top three in Brownlow betting, clearly going to be Melbourne’s best and fairest winner this season and he is one of the great players in our competition.”
King added that Zurhaar could be one pre-season away from taking a massive step in his career.
“I’m watching the Kangaroos game and I’m thinking ‘Cam Zurhaar, what are you waiting for?’ You’ve played 40-odd games of footy and you’re 22 years of age,” he said.
“Is your body getting to the same shape as a Christian Petracca? And I’m not going to judge you today because this year has been a difficult year and clearly the hub life has an impact on all those things.
“This is one of the reasons he can only play in the midfield for 10 minutes because you can’t cover the ground. Now Petracca went through that, Rayner went through that and he is turning the corner.
“I want to judge the first time we see Cam Zurhaar in 2021, when we see a photo in January, I want to see him be the Christian Petracca of 2020.
“Every club has got them. I’m just saying Zurhaar because I noticed it.”
