he's not johns ... but he is cronkish
At the same age Johns wasn't yet Johns either. By the time he was the age Cleary is now he had achieved this:
66 games (36 wins including 2 from 3 in the finals)
6 Origins (4 wins)
But he was only 3 months from starring in the 1997 finals series. Is Nathan Cleary about to star in the finals? We'll sure as shit find out soon.
Cleary has achieved this:
96 games (58 wins including 3 from 6 in the finals)
5 Origins (3 wins)
Given how good Johns was, Cleary is unlikely to be as good, but I suspect he will be better than Cronk. Here's Cronk's achievements by the age of 22 years and 10 months:
33 games (17 wins including 1 from 3 finals) mostly off the bench
0 origins
