An argument could be made that Cleary wasn't in top five halves this year, but if you take the past three seasons into account, there's been very few better.
In fairness to Nathan, he had all the excuses in the world to pack it in. That knee injury was set to rub him out of the first Origin game, but he forced his way into the side and while he didn't star for NSW he didn't look out of place either.
Then when he gets back to Panthers, the side is a shambles with Gould looking for any excuse to fire Griffin and players falling down left, right and centre. Even with some of the players they had like Campbell-Gillard and Maloney, it was obvious they weren't 100% and really should have pulled the pin, but they kept pushing anyway.
I see Nathan as the new mould of halfback. Gone are the days of the Andrew Johns, Johnathan Thurstons and the instinct players who play eyes up footy. The modern game is too structured for it, some it comes down to who has the most god given talent. Right now very few can compete with Cleary's kicking and passing game. His running game was also showing some great signs towards the end of the season and he was beginning to make the type of plays you'd expect from your champions. When the chips were down for Penrith, Cleary was still head and shoulders their best player (eg. vs. Warrior @ Auckland).
As far as Pearce goes, he's a quality halfback and a cautionary tale wrapped up into one. He should have never been guaranteed an Origin jersey like he was and in retrospect, he wasn't ready for Origin until 2013 if ever.
