He just cannot handle the pressure and expectations, he is good at club level, won a premiership but soon as he gets in origin he can't deliver anything meaningful.
His long kicking game being average can be explained by lack of forward platform but the first good attacking opportunity the blues get he passes it into the backside of a decoy runner and turns it over. Several times he has poor passes to players who coughed it up and he came out of the line at 12-6 and gifted munster a line break to pretty much finish the game off when the blues where actually looking like they might be getting on top.
After all the origins he had played he has not had even a 5 minute period when he took control and made something happen, any of his highlights are basic backing up for a try after someone has broken the line or passing to someone who beats his man individually, and they're far outweighed by basic errors and brain explosions at critical times.
Not only does he really offer nothing to the team he genuinely handicaps them, they would be a better team just putting a solid mobile back rower there and letting maloney and hayne float around trying to create something.
