Cleary carves up NRL teams where there are weak defenders sprinkled among the opposition but he is yet to do much at rep level. It's evidence that he benefits from playing in a club side that is much better than its opponents, including in finals matches. His team goes forward, completes its sets, and gives him plenty of time and space to execute his plays.
Yes he's better than Moses but it's because he is bigger and stronger. Moses often needs to make the big play because if he just dummies and takes on the defence 20+ times a game he will get a bunch of slow play-the-balls. Cleary generally plays the ball quickly so he can afford to run a lot, like Dylan Brown at his best.
I would argue that on terms of skills alone, Moses is his equal - possibly even better. Maybe.
But what separates Cleary from Moses is his mentality - never flustered, always composed, and demanding the ball when his team needs a spark.
Cleary is a genuine leader, and a genuine "give the ball, and I'll make something happen" player.
Yes, he plays in a team stacked with talent.
But he's stood up when this same stacked team has been down for the count so many times.
He's easily worth what he's being paid, and more.
